AllerAir AirMedic Pro 5 HD MCS Air Purifier (Chemical Sensitivity, Heavy VOC and Odor Load)
airflow
(3.5" deep bed)
at 0.1 microns
The AllerAir AirMedic Pro 5 HD MCS pairs AllerAir's chemical-sensitivity build with the deepest practical carbon load in the Pro 5 line. AllerAir replaces the parts of a standard purifier most likely to off-gas on their own: a powder-coated carbon canister and body, a Super HEPA filter made without glues or binders, unbleached organic cotton pre-filters, and no rubber gaskets.
On top of that build sits a 3.5-inch carbon bed holding 22 to 24 pounds of activated carbon and a Super HEPA filter that captures 99.99% of particles down to 0.1 microns. That's the setup for heavy VOC exposure, renovation and off-gassing fumes, smoke infiltration, and strong or persistent chemical odors in a household where the purifier itself can't introduce a new smell.
How the Pro 5 HD MCS Compares: Pro 5 MCS vs Pro 5 HD MCS
Both share the same MCS-specific build: powder-coated canister and body, organic cotton pre-filters, no rubber gaskets, and a particle filter free of glues and binders. They separate on carbon depth and particle filtration. The Pro 5 MCS carries a lighter carbon bed with medical HEPA. The Pro 5 HD MCS carries a much deeper carbon bed and finer Super HEPA for heavier chemical or odor loads.

Choose the Pro 5 HD MCS when you need the MCS-safe construction and your chemical, off-gassing, or odor load is heavy or persistent. The Pro 5 MCS is the more affordable call when the same construction is what matters most and your VOC or odor exposure is moderate rather than severe.
Don't need the MCS-specific construction and just want the most carbon for VOCs? The Pro 5 Ultra carries a 5" carbon bed with a choice of Exec or Vocarb blend. Not sure which one fits your situation? Tell us what you're sensitive to and we'll help you decide.
Coverage is based on 8-ft ceilings and AllerAir's recommended two air changes per hour. AllerAir sizes its units by room volume, so contact us if you want help matching a unit to your space. Sound levels vary by fan speed.
Is the AllerAir AirMedic Pro 5 HD MCS Right for You?
The Pro 5 HD MCS is for people managing multiple chemical sensitivity who also face a heavy or ongoing chemical and odor load, where both the materials the purifier is made from and the amount of carbon it carries matter.
It's an especially strong fit if you:
✔Manage multiple chemical sensitivity (MCS) and need a unit that doesn't off-gas on its own
✔Are dealing with heavy VOC exposure from active renovation, fresh paint, or new flooring and cabinetry
✔Have persistent chemical odors, smoke infiltration, or off-gassing that a lighter carbon bed can't keep up with
✔Are sensitive to fragrance, rubber, or synthetic materials used in standard appliances
✔Want the finer Super HEPA filter for fine dust, smoke particulate, and mold spores
Great fit for:
✔Bedrooms, home offices, and open living areas up to 1,500 sq ft
✔Recently renovated or actively renovating homes still off-gassing
✔Chemically sensitive households where standard purifiers have caused reactions
✔Apartments and studios with smoke or chemical infiltration from neighboring units
✔Artists' and hobby studios with solvent, resin, or adhesive fumes
What the AllerAir AirMedic Pro 5 HD MCS Removes
Particles & Allergens (Super HEPA)
Air passes through a Super HEPA filter certified to capture 99.99% of airborne particles down to 0.1 microns, finer than a standard HEPA:
- Fine dust and combustion particles, including smoke particulate
- Pollen and seasonal allergens, common triggers for allergy and asthma
- Pet dander, the airborne skin flakes from cats and dogs
- Mold spores, captured before they settle and spread
Chemicals, Gases & Odors (Activated Carbon)
Before air reaches the HEPA, it passes through a 3.5-inch bed holding 22 to 24 pounds of activated carbon. Carbon adsorbs gases and odors that particle filters cannot touch:
- VOCs and chemical fumes from paint, furniture, flooring, adhesives, and cleaning products
- Renovation and off-gassing smells from new cabinetry, mattresses, and finishes
- Smoke odor from cooking, fireplaces, or infiltration from neighboring units
- Solvent and hobby fumes from resins, adhesives, and art materials
Key Design Features
Powder-Coated Canister & Body
The carbon canister and unit body carry a powder-coated finish, which cuts down the off-gassing that a chemically sensitive user could otherwise react to.
Binder-Free Super HEPA
The Super HEPA filter captures 99.99% of particles at 0.1 microns and is built without the glues or binders used in standard filters, so the particle stage doesn't add a smell of its own.
No Rubber Gaskets
The unit skips the rubber gaskets found in standard purifiers, since rubber odor is a common trigger for sensitive users.
Unbleached Organic Cotton Pre-Filter
The pre-filter is organic cotton rather than a synthetic fiber pad, catching larger dust and debris without introducing synthetic material into the airstream.
3.5" Carbon Bed, 22 to 24 lb
The deepest carbon load in the MCS line, for heavy VOC exposure, renovation off-gassing, and persistent chemical odors.
Compact Housing on Wheels
At 20.5 inches high and 15 inches across, the Pro 5 HD MCS rolls on four caster wheels, so you can move its 43-pound body near the source of pollutants.
Maintenance & Filter Life
The Pro 5 HD MCS is built to run continuously, and keeping it effective comes down to a simple filter schedule:
- Pre-filter: replace every 2 to 3 months to keep airflow up
- Carbon filter: every 2 to 3 years, with a 5-year shelf life
- Super HEPA filter: every 1 to 2 years
The pre-filter pulls out from the bottom with no tools. The carbon and Super HEPA filters are reached from the bottom with screws. AllerAir recommends running the unit 24/7 on a low setting and placing it near the source of pollutants for best results. For a painting project, unplug the unit and remove the HEPA filter until the job is finished, since paint particles can clog it early.
Genuine replacement filters for the Pro 5 HD MCS are available right here at Pure Indoor Living.
Frequently Asked Questions
What makes this model different from a standard air purifier?
Two things. First, the construction: AllerAir builds the Pro 5 HD MCS with a powder-coated carbon canister and body, a Super HEPA filter made without glues or binders, unbleached organic cotton pre-filters, and no rubber gaskets, so a purifier built for chemically sensitive users doesn't introduce its own off-gassing or rubber odor. Second, the carbon: it carries a 3.5-inch bed with 22 to 24 pounds of activated carbon, the most in the MCS line, for heavy VOC and odor loads.
How is this different from the standard Pro 5 HD?
The filtration is close: the Pro 5 HD also uses a 3.5-inch carbon bed and Super HEPA. What the HD MCS changes is the build. It leaves out the rubber gaskets, uses unbleached organic cotton pre-filters instead of synthetic pads, and pairs them with a Super HEPA filter made without glues or binders, so the purifier itself has less of its own smell. The HD MCS also ships as one fixed configuration, while the standard Pro 5 HD lets you choose a carbon blend and add a UV lamp. Buy the HD MCS if you have reacted to a standard purifier before or know you are sensitive to those materials. The standard Pro 5 HD is the better value if you just want the carbon and particle filtration.
Will it clear the air while a renovation is still going on?
It helps, but run it the right way. Keep it in the room you spend the most time in rather than the active work area, and place it away from heavy dust so the pre-filter and carbon last. During sanding, demolition, or spraying, close off the work zone if you can. Once the messy work is done and the space is mostly off-gassing, move it into that room and let it run continuously. If you are painting, unplug it and pull the HEPA filter until the paint has dried, since fresh paint mist clogs the HEPA early.
How loud is it?
The Pro 5 HD MCS runs at 39 dB on its lowest speed, quiet enough for most people to sleep near, and 62 dB on high when you want to clear a room fast. The variable-speed control lets you set it anywhere in between.
Can I run it 24/7?
Yes, it's built for continuous operation, which is how AllerAir recommends using it. Running it on low near the source of pollutants is the simplest way to keep air quality steady.
Does the Pro 5 HD MCS produce ozone?
No. The Pro 5 HD MCS cleans air by filtration only: a pre-filter, activated carbon, and Super HEPA. There's no ionizer and no ozone-generating process, which matters for a unit built around sensitivity.
Where do I get replacement filters?
Genuine AllerAir replacement filters for the Pro 5 HD MCS are available here at Pure Indoor Living. The pre-filter changes every 2 to 3 months, the carbon filter every 2 to 3 years, and the Super HEPA filter every 1 to 2 years.
What's the warranty?
The Pro 5 HD MCS comes with AllerAir's 10-year limited warranty. That covers repair of defective components for 5 years from delivery, including labor, plus an additional 5 years on parts. Expendable items like pre-filters and filters aren't covered, and the warranty is for the original purchaser.
Is this a medical device?
No. The AllerAir AirMedic Pro 5 HD MCS is a residential and commercial air purifier for general indoor air quality. It's not a medical device and isn't intended to diagnose, treat, cure, or prevent any disease or health condition.
