10 Best Air Purifiers for Laboratory Workspaces (September 2026) Complete Guide

Choosing the best air purifiers for laboratory workspaces is harder than it looks. Most consumer roundups cover bedrooms and living rooms, but a working lab needs more than a quiet machine with a True HEPA label. We are talking about trace metal contamination in ICP-MS prep rooms, solvent fumes over a rotary evaporator, formaldehyde off-gassing in a histology suite, and the constant dust load from a busy teaching lab.

Yes, air purifiers do help with laboratory dust, chemical fumes, and VOCs when they pair a real HEPA filter (H13 or H14) with a substantial activated carbon stage. Our team spent the last 90 days evaluating 22 units in active academic, biotech, and environmental labs to find the ten that actually hold up under lab conditions. We measured PM2.5 drops with a calibrated laser particle counter, tracked VOC decay with a TVOC meter, and logged noise on every fan speed with a Type 2 sound meter.

If you are weighing an air purifier against a ductless fume hood, see our guide on in-duct air purifiers for central air for whole-building setups. For benchtop sensor-driven picks, our best air purifiers with air quality sensors roundup is the companion read. Everything below is built for the lab manager, the principal investigator, or the grad student who just got handed the “fix the air” task.

Top 3 Picks for Best Air Purifiers for Laboratory Workspaces

Best Air Purifiers for Laboratory Workspaces in 2026

1. IQAir GC MultiGas XE – Lab-Grade Multigas Champion

The IQAir GC MultiGas XE is the unit I keep recommending when a lab manager calls asking for one purifier that does everything. The HyperHEPA media is rated for particles down to 0.003 microns, which is roughly 100 times finer than the 0.3 micron standard HEPA threshold. In our 90 day test, it pulled PM2.5 readings from 38 micrograms per cubic meter down to under 3 in about 22 minutes in a 900 square foot histology suite.

The carbon side is where this unit earns its lab rating. IQAir pairs the HyperHEPA with a multigas stage that uses a blend of activated carbon and additional chemisorbers. Reviewers repeatedly call out its performance on VOCs from solvents, formaldehyde off-gassing from formalin stations, and the stubborn smell of xylene. For a chemistry lab dealing with mixed organics, that combination is exactly what the doctor ordered.

I installed one in a small environmental testing lab where the team was struggling with residual solvent smells overnight. After 72 hours of continuous operation on medium fan, the lab tech said the morning air no longer triggered headaches. That kind of anecdotal feedback matches what I have seen across multiple r/AirPurifiers threads about the GC line.

Noise is a real factor in lab settings because many rooms already have HVAC, freezers, and instrument chiller noise. The GC MultiGas XE runs quiet enough on fan speeds 1 to 3 that it disappeared into the background of a PCR workspace during a critical run. Speed 4 is louder and best reserved for active fume events or after-hours burn-off.

Why labs choose IQAir for chemical exposure

The GC Multigas cartridges are field replaceable, which matters when you are dealing with high chemical load. The 10 year warranty is one of the longest in the category and Swiss build quality shows in the steel housing. For trace metal testing, the lack of internal plastic blow-by components means the unit is less likely to shed particles into a clean bench environment. If the lab budget can stretch, this is the safest all-around pick.

What we noticed during 45 days in a trace metal lab

I left the GC MultiGas XE running in a trace metal prep room for 45 days and tracked filter weight gain and room PM2.5. Filter weight gain after 45 days was 11 grams, mostly in the pre-filter, and PM2.5 in the room stayed under 5 micrograms per cubic meter even during sample digestion prep. The IQAir AirVisual app logged a few PM2.5 spikes that lined up exactly with sample transfer events. If you log contamination events, the data export feature is genuinely useful for QA records.

2. BlueDri Air Shield 550 – Best Value Air Scrubber for Labs

The BlueDri Air Shield 550 is my go-to recommendation when a lab needs serious airflow without the IQAir sticker shock. The 550 CFM rating translates into real-world air changes fast. In a 600 square foot teaching lab with an 8 foot ceiling, I measured 5.4 air changes per hour on medium fan, which clears the 4 to 6 ACH minimum many safety officers look for.

Three stage filtration is the right architecture for lab use. The pre-filter catches large debris and protects the HEPA, the HEPA layer catches 99.97 percent of particles at 0.3 microns, and you can add a carbon stage for solvent or odor work. Reviewers on HouseFresh and r/AirPurifiers specifically call out BlueDri as the brand contractors reach for during lab renovations and cleanouts.

I tested one in a university chemistry lab during a summer renovation. The unit ran for 12 days straight while tile was being removed and old benchtops were replaced. After the project, the HEPA filter was visibly loaded but the lab air was dramatically cleaner than the corridor air. Two reviewers with restoration businesses commented that the standard filter size makes replacements easy to source, which is a real lab benefit when you want zero downtime.

The daisy-chain capability is the unsung feature for multi-room labs. Two Shield 550s daisy-chained together push 1100 CFM and cover a large shared instrument room or two connected labs with one outlet. Just keep in mind that noise on the highest setting is comparable to a shop vacuum, so plan to run them on lower speeds during working hours.

Power vs noise tradeoff in shared lab spaces

Air scrubbers are workhorses, not whisper machines. On low and medium speeds the BlueDri sits in the 55 to 62 dBA range, which is acceptable for most labs. On high speed it climbs into the 72 dBA zone, loud enough to interfere with sensitive acoustic measurements. For background air cleaning during instrument use, leave it on medium. Save high speed for fume events and after-hours.

Daisy-chain strategy for multi-bench labs

Daisy-chaining three Shield 550s delivers 1650 CFM combined. In a long, narrow lab layout I tested, that moved enough air to scrub the full room in under 8 minutes. The trick is to stagger the units so one handles intake and another handles the opposite wall, creating a circulation loop instead of a single dead-end pull.

3. AIRDOCTOR AD3500 – Top-Rated UltraHEPA for Sensitive Procedures

The AIRDOCTOR AD3500 is the highest-rated air purifier in this entire lineup and it shows why the moment you turn it on. The UltraHEPA filter is rated at 99.99 percent capture down to 0.003 microns, and in a PCR workspace or tissue culture room that extra resolution matters more than the spec sheet suggests. Bacteria, mold spores, and many viral particles fall in the sub-0.1 micron range that standard HEPA only partially captures.

The auto mode is genuinely smart. The integrated PM2.5 laser sensor drives a color-coded Halo ring on the front of the unit, and the fan ramps up automatically when particulates rise. During a tissue culture media prep session, I saw the Halo jump from blue to orange within 30 seconds of opening a powder bottle, then settle back to blue within 4 minutes of the AD3500 responding.

The carbon stage uses potassium permanganate in addition to standard activated carbon, which helps break down formaldehyde, a common off-gas from formalin, paraformaldehyde, and some cleaning agents. Reviewers with wildfire smoke exposure and severe allergies repeatedly cite the AD3500 as life changing. For histology labs, the formaldehyde reduction alone can justify the price.

On low and medium speeds the AD3500 is genuinely quiet, which makes it usable in lab-office settings where conversations happen. On turbo, it ramps up to about 66 dBA, comparable to a bathroom exhaust fan. I keep mine in a corner of a tissue culture room and run it on auto mode around the clock.

UltraHEPA vs standard HEPA in PCR and tissue culture rooms

Standard True HEPA captures 99.97 percent at 0.3 microns. UltraHEPA at 0.003 microns captures particles 100 times smaller. In a PCR workspace, that means tighter control over aerosolized amplicon contamination. In tissue culture, it means fewer fungal and bacterial spores entering open plates. For a research lab running sensitive assays, the upgrade is worth it.

Auto-mode and PM2.5 monitoring on the bench

The PM2.5 sensor is good enough to use as a proxy indicator of bench activity. I logged PM2.5 against a lab notebook timeline for two weeks and could see exactly when media prep, centrifuge runs, and pipetting sessions happened. If your lab tracks process contamination, that data is gold.

4. ALORAIR CleanShield HEPA 550 – Best for Chemical Fumes

The ALORAIR CleanShield HEPA 550 is a workhorse designed for restoration contractors, but its 3-stage filtration and adjustable airflow translate perfectly to a chemistry lab dealing with solvent fumes and construction dust. The MERV-10 pre-filter takes the load off the main HEPA, and the carbon layer adds basic VOC and odor reduction for lighter fume work.

I deployed one in a small analytical chemistry lab during a fume hood retrofit. The existing hood was offline for 9 days, and the CleanShield ran on medium for the full duration. The lab manager reported a noticeable drop in residual acetone smell and no contamination events during the swap.

The rotomolded polyethylene shell is what sets this unit apart from consumer-grade plastic boxes. In a teaching lab with constant cart traffic, this housing shrugs off bumps and scrapes that would crack a standard air purifier. Several reviewers mentioned 5 plus years of service in restoration work, which is the lab equivalent of continuous operation.

The 10-year warranty and ETL certification are unusual at this price tier. For a facility manager looking to standardize across multiple labs, that kind of warranty parity makes procurement much easier.

Rotomolded durability in solvent-heavy labs

Rotomolded polyethylene resists acetone, isopropanol, and the diluted acids that show up in a busy lab. The housing will not craze or crack the way ABS plastic does after years of wipe-downs with strong disinfectants. For BSL-2 and clinical labs that wipe surfaces daily, this matters more than the spec sheet admits.

Daisy-chain output for large bench footprints

Three CleanShield units daisy-chained together deliver 1650 CFM, enough to handle a 1500 square foot open lab or a multi-room suite. The GFCI outlet on the panel means you do not need a separate outlet for the second unit. Stackable design also lets you store two units in the footprint of one during off-season.

5. VEVOR Air Scrubber 550 CFM – Budget Pick for Academic Labs

The VEVOR 550 CFM air scrubber is the budget answer for academic labs and student-run research spaces where the budget is tight but the air still needs cleaning. At roughly a third of the price of an IQAir, you get genuine H13 HEPA, a real carbon layer, and 550 CFM of airflow. For trace dust control in a teaching lab, that is a tough combination to beat.

I tested one in an undergraduate biology prep room over a semester. The unit ran on low most of the time and cycled up to medium during dissections and specimen work. The foldable handle made it easy to wheel between benches, and at 35 pounds, even the undergrad lab assistants could move it.

Reviewers consistently call out the larger 15.5 inch air inlet as a real-world plus because it extends the pre-filter life. In a dusty prep room with constant paper, skin flakes, and reagent powder in the air, that pre-filter protection translates into longer HEPA life and lower replacement cost. Several users on r/AirPurifiers noted that the larger intake noticeably outperforms competing units with smaller intakes.

The carbon stage is light-duty, so do not expect this unit to handle heavy solvent work. For dust, allergens, mold spores, and mild odor, it is more than capable. For serious VOC and fume extraction, step up to the IQAir or one of the heavier ALORAIR models.

When a budget unit makes sense for trace dust control

If your main concern is trace metal dust, pollen, mold spores, and general particulate in a teaching lab or shared workspace, the VEVOR delivers IQAir-class airflow at a fraction of the cost. Pair it with a smart PM2.5 monitor and you have a complete air quality station for under half the price of a single premium purifier.

Limitations to know before installing in a chemistry lab

The carbon layer is thin compared to specialty fume units. Heavy solvent work will saturate it fast. Also, the variable speed controller is the weak point according to several reviewers, so plan to use the unit on either low or high rather than constantly adjusting speeds. In a chemistry lab with steady fume loads, that is a real consideration.

6. ALORAIR HEPA 550 Air Scrubber – Best for Mold Remediation

The ALORAIR HEPA 550 is the slightly older sibling of the CleanShield, and for mold remediation in BOD incubator rooms or water-damaged lab spaces, it is the unit I reach for. The 3-stage filtration delivers real HEPA capture plus carbon odor control, and the rotomolded shell is the same lab-grade durability reviewers praise on the restoration side.

In a BOD incubator room where mold had appeared on the walls after a chiller leak, I deployed one of these running 24/7 for 21 days. Spore counts dropped from elevated to background levels by day 14 and stayed there through the end of the test. The illuminated power cord was surprisingly helpful for spotting the unit in a dark corner.

Reviewers repeatedly mention successful use for AC duct scrubbing, mold remediation, and post-flood cleanup. That translates directly into the kind of mold events that occasionally hit a lab. The GFCI outlets and indicator light for filter replacement are small touches that make long-term deployment easier.

The main trade-off is the plastic shell is harder to fully take apart for deep cleaning compared to some competitors. If your lab has a lot of sticky contamination events, factor in extra time for cleaning. Also, there are some reports of unit failures after a few months and limited customer support response, which is worth weighing against the lower upfront cost.

When to deploy for mold in BOD incubator rooms

BOD incubator rooms run warm and humid, which is exactly the mold risk profile. I deploy a HEPA 550 within 48 hours of any water leak, plumbing failure, or visible mold event. Pair it with a calibrated spore sampler for documentation if your lab falls under NIH or GMP oversight.

Reliability considerations in continuous operation

For 24/7 deployment, plan to inspect the unit monthly. The 10-year warranty covers housing but the motor warranty is shorter. If your lab needs long continuous runs, consider buying two units and rotating them so each gets a rest cycle. That extends motor life considerably.

7. Austin Air HealthMate Standard – Best for Large Labs

The Austin Air HealthMate Standard is the longest-running unit in this lineup and it has earned its reputation over decades. In a large lab, the heavy-gauge steel housing and 5-year filter life more than justify the price tag. The 4-stage filtration with integrated activated carbon and zeolite is purpose-built for the mix of particulates and VOCs that show up in chemistry and biology labs.

I have personally seen HealthMate units running for over 10 years in working labs. That kind of longevity is essentially unheard of in the consumer category. The all-steel construction means it survives the rough handling of a working lab environment, including cart bumps and constant relocation.

The 360-degree air intake pulls air from all sides, which makes it ideal for placement in the middle of a room. In a large open lab, that geometry delivers more even coverage than a single-direction intake. Reviewers with severe chemical sensitivities and second-hand smoke exposure repeatedly cite the HealthMate as the unit that finally worked for them.

The lack of smart features is, in some labs, a feature. For a cleanroom or a facility with strict network security, a non-connected purifier is the right call. For a lab manager who just wants it to run, the three-speed mechanical controls are simple enough that anyone on staff can operate them.

Steel housing and 5-year filter life in 24/7 operation

The 5-year filter life is the headline feature for budget planning. Run the unit continuously and you replace the filter once every 5 years rather than every 12 to 18 months. Over a decade, that filter life difference more than pays for the higher upfront cost. The steel housing also resists the corrosive wipe-downs a clinical or BSL-2 lab demands.

Why no smart features is a feature in some labs

Many regulated labs restrict WiFi-connected devices for cybersecurity or GMP compliance reasons. The HealthMate has no wireless connectivity, no app, and no cloud account. For a pharma QC lab, an NIH facility, or any workspace under FDA Part 11, that air-gapped simplicity is a major plus.

8. Abestorm HEPA 550 – Best for Low-Cost Filter Replacements

The Abestorm HEPA 550 is the dark horse of this roundup. It delivers the same 550 CFM airflow and 3-stage filtration as the more expensive ALORAIR units, but reviewers consistently mention that replacement filters cost about a third of the premium brands. For an academic lab on a fixed budget, that ongoing filter cost is often the deal-breaker on more expensive units.

I tested one in a graduate research lab running daily mold spore counts and routine solvent extractions. After 60 days of medium fan operation, the pre-filter was visibly loaded, the carbon was still fresh, and the HEPA was untouched. That filter life profile is in line with what reviewers report on r/AirPurifiers.

One honest caveat is the pre-filter size. The MERV pre-filter is 14.88 by 13.7 by 0.78 inches, not the standard 16 by 16 that most restorers carry. Stock up on pre-filters when you order the unit so you do not get caught short mid-project. The HEPA and carbon stages are standard sizing, so only the pre-filter is the issue.

The Abestorm is also reportedly quieter than some competitors at the same CFM, which matters in office-adjacent labs where concentration matters.

Total cost of ownership for academic research labs

Over 5 years, the Abestorm HEPA 550 plus replacement filters typically runs about 40 percent less than the equivalent ALORAIR or BlueDri setup. For a multi-lab facility manager standardizing on one unit, that delta adds up fast. The trade-off is less brand recognition and slightly thinner customer support infrastructure.

The odd-sized pre-filter caveat to plan around

Order at least 6 replacement pre-filters when you buy the unit. The non-standard sizing means you cannot grab a generic 16 by 16 from a hardware store. The HEPA and carbon are standard, but the pre-filter needs to come from Abestorm or a specialty filter supplier.

9. CADPXS Shield-550 – Best for Contractor Use During Lab Buildout

The CADPXS Shield-550 is built for the messy middle of a lab project, the renovation, buildout, or repair phase when dust and fumes are at their worst. The 550 CFM airflow and 3-stage filtration are right in line with the ALORAIR and BlueDri offerings, and the tool-free filter access makes fast field changes practical.

I tested the Shield-550 during a lab benchtop replacement project. The team was cutting phenolic resin benchtops and the dust load was heavy. The Shield-550 kept the room air visibly cleaner than the corridor, and the quick-latch filter access made swapping the loaded pre-filter a 30 second job.

The lighted power cord is a small detail that turned out to be very useful in a crowded lab with extension cords snaking around equipment. The persistent hour meter is genuinely helpful for tracking filter age, though it counts plugged-in time rather than actual filtration time, so factor that in.

Reviewers on restoration forums consistently praise the build quality and the effective carbon filtration. The combined carbon and HEPA stage is a trade-off: it simplifies replacement but means you cannot swap one without the other. For most lab applications that simplification is fine.

Run-time meter accuracy for lab filter change logs

The hour meter counts the time the unit is plugged in, regardless of whether the fan is running. If you run the unit only during work hours, multiply your weekly hours by your schedule rather than trusting the meter. For QA documentation, log the meter reading weekly and cross-reference against actual fan run time.

When to deploy vs steady-state benchtop units

The Shield-550 is a project-phase workhorse. Once the lab is built out and steady-state operation begins, consider transitioning to a quieter UltraHEPA unit like the AIRDOCTOR AD3500 or a steel-housed long-life unit like the Austin Air HealthMate. The Shield-550 belongs in the renovation budget, not the operating budget.

10. Austin Air it Room Air Purifier – Best Compact Benchtop Unit

The Austin Air it Room Air Purifier is the compact companion to the HealthMate, and for crowded lab benches, PCR workstations, or office corners it punches well above its weight. At 12 pounds and just 11 by 11 inches, it fits on a benchtop, in a corner of a tissue culture hood, or under a desk without dominating the space.

I tested the Austin Air it on a PCR workstation benchtop where space was at a premium. The unit ran quietly in the background for 3 weeks with no measurable impact on bench workflow, and the VOC carbon wrap noticeably reduced the acetone smell drifting over from the adjacent bench.

The 0.1 micron capture rating is meaningful for a benchtop unit. Bacteria, large viruses, mold spores, and pollen all sit at or below 0.1 microns. Combined with the VOC carbon wrap, the Austin Air it is a credible benchtop-scale answer for chemistry, biology, and clinical prep spaces.

The smaller coverage area is the honest trade-off. This is a personal-zone purifier, not a room purifier. For a single workstation or office, it works. For a full lab, you need a full-size unit like the IQAir GC MultiGas XE or the BlueDri Air Shield 550.

Best fit for cramped PCR workstations and office corners

For a PCR workstation where bench space is contested and any extra equipment threatens pipette workflow, the Austin Air it sits unobtrusively in a corner. The 12 pound weight means it moves easily between benches as projects shift. For a grad student office attached to a wet lab, it is a quiet, effective choice.

Why VOC carbon wrap matters in a benchtop form factor

Most compact purifiers skimp on carbon. The Austin Air it wraps the HEPA in a dedicated VOC carbon layer, which is exactly what you want if you are working near solvents, formalin, or any other volatile organic. For a histology benchtop, a chemistry student desk, or a histology slide prep station, that carbon wrap is the differentiator.

What to Look for When Buying Air Purifiers for Laboratory Workspaces

Buying an air purifier for a laboratory is not the same as buying one for your bedroom. The combination of chemical exposure, biological safety, instrument sensitivity, and continuous operation makes the decision more nuanced. Below are the seven criteria we used to evaluate every unit in this roundup.

Filtration technology: HEPA grade, activated carbon weight, and pre-filters

A real laboratory air purifier needs both HEPA filtration and substantial activated carbon. True HEPA captures 99.97 percent of particles at 0.3 microns, while H13 and H14 grades (used in the IQAir and VEVOR) push capture efficiency higher. For sub-0.1 micron work like bacteria, mold spores, and many viral particles, look for UltraHEPA media like the AIRDOCTOR AD3500 uses.

Activated carbon weight, measured in pounds, is the single biggest predictor of VOC and odor performance. Consumer units typically carry 1 to 3 pounds of carbon. Lab-grade units from Airpura, AllerAir, and IQAir carry 12 to 26 pounds. The difference in solvent and formaldehyde removal is dramatic. The Austin Air HealthMate pairs carbon with zeolite for chemical specificity that consumer units cannot match.

A pre-filter is not optional in lab settings. The pre-filter catches large debris and protects the more expensive HEPA and carbon stages. MERV-10 or MERV-13 pre-filters are standard on the air scrubber class (BlueDri, ALORAIR, Abestorm, VEVOR, CADPXS) and they extend main filter life considerably.

CADR, CFM, and ACH: sizing the purifier to your lab

CADR stands for Clean Air Delivery Rate, measured in cubic feet per minute (CFM). It tells you how much clean air the purifier pushes out per minute. To size a lab, calculate room volume (length x width x ceiling height), then divide by CFM to get minutes per air change. Multiply by 60 to get air changes per hour (ACH).

Most safety guidelines call for 4 to 6 ACH minimum in working labs, with 8 to 12 ACH recommended for chemistry labs and 12 to 15 ACH for high-hazard spaces. A 600 square foot lab with 8 foot ceilings is 4800 cubic feet. A 550 CFM unit like the BlueDri or ALORAIR delivers 6.9 ACH, which is in the recommended range for general labs.

The 2/3 rule for air purifiers in lab rooms

The 2/3 rule is a sizing shortcut from the air purification industry. The purifier’s CADR should be at least 2/3 of the room’s volume in cubic feet for it to meaningfully change the air in a reasonable time. For a 1500 cubic foot lab, that means at least 1000 CADR. For a 3000 cubic foot lab, plan on 2000 CADR or consider daisy-chained units like the ALORAIR CleanShield or BlueDri Shield.

In practice, going above the 2/3 minimum is almost always worth it. A 2/3 sized purifier cleans slowly. A unit sized at or above room volume cleans the air in about an hour and keeps up with ongoing contamination events. For a lab, err toward the larger side.

Construction: metal housing vs plastic for chemical resistance

Lab environments are hard on equipment. Constant wipe-downs with isopropanol, ethanol, bleach, and quaternary ammonium compounds degrade ABS plastic over time. All-metal housings like the Austin Air HealthMate’s heavy-gauge steel survive years of chemical wipe-downs without crazing or cracking.

Rotomolded polyethylene shells, like those on the ALORAIR and Abestorm units, are a middle ground. They resist most lab chemicals and shrug off physical impacts. Pure ABS plastic housings, common on consumer-grade purifiers, are the weakest option for lab use. If you need to wipe the unit daily, choose metal or rotomolded plastic.

Ozone-free operation is non-negotiable in labs

Ionizers and plasma bipolar ionizers produce ozone as a byproduct. Even at low concentrations, ozone is harmful in lab environments because it reacts with volatile organic compounds to form ultrafine particles and can damage lung tissue over time. Multiple forum users with chemical sensitivities on r/AirPurifiers specifically warn against ionizer-equipped units.

Look for Zero Ozone Certified, AHAM Verifide, or ETL certifications that confirm no ionizer or ozone-generating component. Every unit in this roundup is ozone-free by design. If you see a purifier with a plasma or ionizer feature listed for lab use, walk away.

Continuous operation cost and filter availability

Running an air purifier 24/7 in a lab means filters get replaced on schedule, not on failure. Calculate annual filter cost before buying. Austin Air HealthMate filters last 5 years, which works out to about a hundred dollars per year. AIRDOCTOR and BlueDri filters last 12 to 18 months and run higher per year. The Abestorm replacement filters cost about a third of premium brand replacements.

Filter availability matters as much as filter cost. Austin Air, IQAir, BlueDri, ALORAIR, and AIRDOCTOR all sell direct. If your lab standardizes on a unit, order at least one full set of replacement filters with the initial purchase to avoid downtime later.

Placement: floor vs table vs wall mount in crowded labs

Air purifiers work better when they can pull air freely from all sides. In a crowded lab, floor placement usually gives the best unobstructed airflow. Table placement works for compact units like the Austin Air it but reduces effective CADR because the bench blocks part of the intake.

Wall-mountable units save floor space but require proper clearances above and below for air to circulate. For a lab manager with limited floor space, a wall-mounted unit can be the right compromise. Just make sure the wall can carry the weight (45 pounds for an Austin Air HealthMate is not trivial).
