AllerAir AirMedic Pro 5 MCS Air Purifier (Built for Chemical Sensitivity)
airflow
(2" deep bed)
at 0.3 microns
The AllerAir AirMedic Pro 5 MCS is built specifically for people managing multiple chemical sensitivity, not just for stronger filtration. AllerAir swaps out the parts of a standard purifier most likely to off-gas on their own: a powder-coated carbon canister and body, a metal-cap HEPA filter with no rubber gaskets, and unbleached organic cotton pre-filters.
It still does real filtration work, with a 16-pound activated carbon canister and medical-grade HEPA that captures 99.97% of particles down to 0.3 microns. That's built for VOCs, chemical off-gassing, fragrance and cleaning-product sensitivity, and renovation fumes, in a unit that doesn't introduce its own chemical smell out of the box.
How the Pro 5 MCS Compares: Pro 5 MCS vs Pro 5 HD MCS
Both share the same MCS-specific build: powder-coated canister and body, no rubber gaskets, organic cotton pre-filters. 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 deeper carbon bed and Super HEPA for heavier chemical or odor loads.

Choose the Pro 5 MCS when the MCS-safe construction is what you need, and your VOC or odor load is moderate rather than severe. The Pro 5 HD MCS is the better call when chemical exposure, off-gassing, or odors are heavier, since it carries more carbon and a finer Super HEPA filter in the same MCS-safe build.
Don't need the MCS-specific construction and just want maximum 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 MCS Right for You?
The Pro 5 MCS is for people managing multiple chemical sensitivity or fragrance sensitivity, where the materials the purifier itself is made from matter as much as what it filters out.
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 sensitive to fragrance, rubber, or synthetic materials commonly used in standard appliances
✔Deal with VOCs and chemical odors from renovation, cleaning products, or off-gassing furniture
✔Want a purifier built with cotton pre-filters instead of synthetic fiber pads
✔Have a moderate, not severe, VOC or odor load
Great fit for:
✔Bedrooms, home offices, and living areas up to 1,500 sq ft
✔Chemically sensitive households where standard purifiers have caused reactions
✔Nurseries and children's rooms where low-off-gas materials matter
✔Recently renovated spaces still off-gassing
✔Fragrance-free households avoiding synthetic materials
What the AllerAir AirMedic Pro 5 MCS Removes
Particles & Allergens (Medical HEPA)
Air passes through a medical-grade HEPA filter certified to capture 99.97% of airborne particles down to 0.3 microns:
- Pollen and seasonal allergens, common triggers for allergy and asthma
- Fine dust and combustion particles, including smoke particulate
- 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 2-inch bed holding 16 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
- Everyday household odors from cooking, pets, and cleaning products
Good to know: if your chemical or odor exposure is heavier than the Pro 5 MCS is built for, the Pro 5 HD MCS carries a deeper carbon bed and finer Super HEPA in the same MCS-safe construction.
Key Design Features
Powder-Coated Canister & Body
Instead of a standard painted or coated finish, the carbon canister and unit body are powder-coated, cutting down the off-gassing that a chemically sensitive user could otherwise react to.
Metal-Cap HEPA, No Rubber Gaskets
The HEPA filter uses a metal cap and skips the rubber gaskets found in standard units, 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.
16 lb Activated Carbon Canister
Adsorbs VOCs, chemical fumes, and household odors before they reach the HEPA stage.
400 CFM of Airflow
Moves the same volume of air as the rest of the Pro 5 line, so it cycles a room of up to 1,500 sq ft several times an hour.
Compact Housing on Wheels
At 20.5 inches high and 15 inches across, the Pro 5 MCS rolls on four caster wheels, so you can move it near the source of pollutants.
Colors & Options
The Pro 5 MCS ships as a single MCS-safe build. You just pick your color:
- Colors: White, Black, and Sandstone, all at the same price.
- No UV-C lamp option. AllerAir does not offer UV on this model.
Maintenance & Filter Life
The Pro 5 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
- HEPA filter: every 2 to 3 years
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 MCS are available right here at Pure Indoor Living.
Frequently Asked Questions
What makes this model different from a standard air purifier?
The filtration is similar to other Pro 5 units, but the materials are different. AllerAir builds the Pro 5 MCS with a powder-coated carbon canister and body instead of a standard finish, a metal-cap HEPA filter with no rubber gaskets, and unbleached organic cotton pre-filters instead of synthetic fiber pads. The idea is that a purifier built for people with chemical sensitivity shouldn't introduce its own off-gassing or rubber odor into the room it's meant to clean.
Why does the Pro 5 MCS use medical HEPA instead of Super HEPA?
The standard Pro 5 MCS pairs its MCS-safe construction with a medical-grade HEPA rated 99.97% at 0.3 microns. If you want that same construction with a finer Super HEPA rated 99.99% at 0.1 microns, plus a deeper carbon bed, the Pro 5 HD MCS is built for that.
How is the Pro 5 MCS different from the Pro 5 HD MCS?
Both use the same MCS-safe construction: powder-coated body, no rubber gaskets, organic cotton pre-filter. The difference is filtration strength. The Pro 5 MCS carries a 2" carbon bed with 16 pounds of carbon and medical HEPA. The Pro 5 HD MCS carries a 3.5" bed with 22 to 24 pounds of carbon and Super HEPA. Choose the HD MCS when chemical exposure or odors are heavier.
Why isn't there a UV-C lamp option?
AllerAir doesn't offer a UV-C lamp on the MCS line. The unit relies on carbon filtration and HEPA particle capture, which fits the model's focus on avoiding added components that could introduce their own sensitivities.
How loud is it?
The Pro 5 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 MCS produce ozone?
No. The Pro 5 MCS cleans air by filtration only: a pre-filter, activated carbon, and medical 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 MCS are available here at Pure Indoor Living. The pre-filter changes every 2 to 3 months, and the carbon and HEPA filters every 2 to 3 years.
What's the warranty?
The Pro 5 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 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.
