AllerAir AirMedic Pro 5 HD Air Purifier (Deep 3.5" Carbon + Super HEPA)
airflow
(3.5" deep bed)
at 0.1 microns
The AllerAir AirMedic Pro 5 HD takes the compact Pro 5 chassis and loads it with the deepest carbon bed in the Pro 5 line and a finer Super HEPA filter. It's built for homes where heavy VOCs, smoke infiltration, or strong chemical odors are the main problem, not a side concern.
It runs a 3.5-inch activated carbon bed holding 19 to 23 pounds of media, and a Super HEPA filter that captures particles down to 0.1 microns. That's the right combination when a standard purifier isn't keeping up with renovation fumes, wildfire smoke drifting indoors, off-gassing from new furnishings, or ongoing chemical exposure in a bedroom, office, or apartment. You still pick the carbon blend, so you can tune it toward general household odors or heavier VOC and chemical control.
How the Pro 5 HD Compares: Pro 5 vs Pro 5 Plus vs Pro 5 HD
All three share the same compact cylindrical AllerAir cabinet, the same 400 CFM airflow, and the same 5-year labor / 10-year parts warranty. They separate on one thing: how much carbon they carry, and how fine the particle filter is. The Pro 5 is the everyday all-rounder. The Pro 5 Plus adds a deeper carbon bed and swaps the medical HEPA for a Super HEPA. The Pro 5 HD carries the deepest carbon bed in the line for the heaviest chemical, smoke, and off-gassing loads.

Choose the Pro 5 HD when heavy VOCs, smoke, or a strong chemical odor are the reason you're buying a purifier, and you want the deepest 3.5" carbon bed in the Pro 5 line plus the Super HEPA that catches particles down to 0.1 microns. The standard Pro 5 is enough if your air is mostly everyday dust, dander, and light odors, and it's the more affordable option with the same airflow. The Pro 5 Plus sits in the middle: the Super HEPA plus a 3" carbon bed, a good fit when odors and VOCs are real but not severe.
Need the same deep carbon in a larger room? The Pro 6 HD pairs a 3.5" bed with 560 CFM airflow and a taller cabinet. Want even more carbon depth? Look at the Pro 5 Ultra and its 5" bed. Dealing with a diagnosed multiple chemical sensitivity? The Pro 5 MCS is built specifically for that job.
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 Right for You?
The Pro 5 HD is for homes where the smell or the chemical load is the whole reason you're shopping, and a standard purifier hasn't been enough, but the room itself isn't oversized.
It's an especially strong fit if you:
✔Notice strong or persistent odors from renovation, smoke, pets, or cooking that don't clear
✔Are managing a chemical sensitivity and need more carbon than a base unit carries
✔Live with ongoing VOC exposure from new flooring, cabinetry, paint, or furnishings
✔Deal with wildfire smoke or other smoke infiltration on a regular basis
✔Want the finer Super HEPA that captures particles down to 0.1 microns, not just 0.3
Great fit for:
✔Bedrooms, home offices, and living areas up to 1,500 sq ft
✔Recently renovated homes still off-gassing months later
✔Apartments where smoke or chemical odors travel in from neighbors
✔Sensitive households where a normal purifier hasn't kept up
✔Homes in wildfire regions that need heavier carbon during smoke season
What the AllerAir AirMedic Pro 5 HD 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, a finer cut than the 0.3-micron medical HEPA on the standard Pro 5:
- Pollen and seasonal allergens, common triggers for allergy and asthma
- Fine dust and combustion particles, including the smallest smoke particulate
- Pet dander, the airborne skin flakes from cats and dogs
- Mold spores, captured before they settle and spread
- Ultrafine particles in the 0.1 to 0.3 micron range that a standard HEPA is less efficient at
Chemicals, Gases & Odors (Activated Carbon)
Before air reaches the HEPA, it passes through a 3.5-inch bed holding 19 to 23 pounds of activated carbon, the deepest bed in the Pro 5 line. Carbon adsorbs gases and odors that particle filters cannot touch:
- VOCs and chemical fumes from paint, furniture, flooring, and household products
- Smoke odor from cigarettes, wildfire infiltration, cooking, or fireplaces
- Renovation and off-gassing smells from new cabinetry, mattresses, and finishes
- Everyday household odors from cooking, pets, and cleaning products
Good to know: if your main concern is heavy VOCs, formaldehyde, or off-gassing from a renovation, choose the Vocarb carbon blend below, which AllerAir tunes specifically for those gases. For a diagnosed multiple chemical sensitivity, the Pro 5 MCS is purpose-built for that job.
Key Design Features
3.5" Deep-Bed Activated Carbon
A full inch more carbon than the standard Pro 5, holding 19 to 23 pounds of media depending on the blend. The extra depth gives gases and odors more contact time, so the unit adsorbs more VOCs before the carbon is spent.
Super HEPA Wrap
A finer particle filter than the standard medical HEPA, certified to 99.99% at 0.1 microns. It wraps the carbon canister and catches the ultrafine particles a 0.3-micron filter lets through more often.
400 CFM of Airflow
The Pro 5 HD moves the same volume of air as the standard Pro 5, so it cycles a room of up to 1,500 sq ft several times an hour.
Quick-Change Pre-Filter
The pre-filter catches larger dust and debris first, which protects the main filters and stretches their life. You can reach it without tools.
Choice of Carbon Blend
You pick Exec for everyday odors and general VOCs, or Vocarb for heavier chemical, formaldehyde, and fume control. Custom blends are available on request.
Optional UV-C Germicidal Lamp
Add a 10-watt UV-C lamp if you want an extra layer of treatment on top of filtration. It's a supplement to the carbon and HEPA, not a replacement for them.
Compact Housing on Wheels
At 20.5 inches high and 15 inches across, the Pro 5 HD is the same size as the standard Pro 5 and rolls on four caster wheels, so you can move it near the source of pollutants.
Carbon Blends & Options
The Pro 5 HD lets you match the unit to your air. You just pick the combination you need when you order:
- Exec (Standard): AllerAir's everyday activated-carbon blend for general household odors and light VOCs, in the deep 3.5" bed. This is the base configuration.
- Vocarb (for VOCs): a carbon blend tuned for higher pollution, chemicals, formaldehyde, fumes, and stronger odors. It's a paid upgrade you select when you order.
- Optional UV-C lamp: a 10-watt germicidal lamp for added treatment. It's an added-cost option and can be combined with either carbon blend.
- Colors: White, Black, and Sandstone, all at the same price.
Not sure which blend fits your air? Exec covers most everyday homes. Reach for Vocarb if you're dealing with fresh paint or flooring, renovation fumes, or ongoing chemical exposure.
Maintenance & Filter Life
The Pro 5 HD 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
- Super HEPA filter: every 1 to 2 years, best changed together with the carbon filter
- Carbon filter: every 2 to 3 years, with a 5-year shelf life
- UV-C lamp (if fitted): every 16,000 hours, or once a year
The pre-filter changes in seconds. For the main Super HEPA and carbon filters, you turn the unit off, unplug it, and open the base with a screwdriver to lift the filters out. AllerAir recommends running the unit 24/7 on a low setting and placing it near the source of pollutants for best results.
Genuine replacement filters for the Pro 5 HD are available right here at Pure Indoor Living.
Frequently Asked Questions
Why does a deeper, heavier carbon filter matter?
Activated carbon works by adsorption: gas and odor molecules stick to the huge internal surface area inside each grain of carbon. Two things decide how well that works. The first is how much carbon there is, because every pound adds surface area and holds more molecules before it's full. The Pro 5 HD carries 19 to 23 pounds in a 3.5-inch bed, against the standard Pro 5's 14 pounds in a 2.5-inch bed. The second is contact time. A deeper bed keeps the air moving through the carbon a fraction longer on each pass, so more of the VOCs and odors get pulled out before the air exits. The practical payoff is that the Pro 5 HD handles a heavier chemical or smoke load and goes longer between carbon replacements. Thin carbon-coated mats, by contrast, saturate quickly and can start releasing trapped odors back into the room.
How is the Pro 5 HD different from the Pro 5 Plus?
Both use the Super HEPA and the same 400 CFM airflow in the same compact cabinet. The difference is carbon depth. The Pro 5 Plus carries a 3" bed with 17 to 18 pounds of carbon. The Pro 5 HD carries a 3.5" bed with 19 to 23 pounds. Choose the Plus for a heavier-than-average odor or VOC load, and the HD when you're fighting a serious, ongoing chemical, smoke, or off-gassing problem and want the most carbon the Pro 5 line offers.
Should I get the Pro 5 HD or the Pro 6 HD?
They use the same 3.5" carbon bed and the same Super HEPA. The difference is airflow and size. The Pro 5 HD moves 400 CFM in a 20.5-inch cabinet, sized for rooms up to 1,500 sq ft. The Pro 6 HD moves 560 CFM in a taller 23.5-inch cabinet for rooms up to 2,000 sq ft. If your problem room is on the larger side or you want faster air turnover, the Pro 6 HD is the better fit for the same filtration.
What does Super HEPA actually do that medical HEPA doesn't?
Both are true HEPA-class filters. The standard medical HEPA on the Pro 5 is rated 99.97% at 0.3 microns. The Super HEPA on the HD is rated 99.99% at 0.1 microns, so it stays highly efficient on the ultrafine particles, like the smallest smoke and combustion particulate, that a 0.3-micron filter passes more of. For a household focused on smoke or fine chemical haze, that finer cut is worth having.
Should I choose Exec or Vocarb carbon?
Start with what's in your air. Exec is AllerAir's everyday blend and it's the right pick for general household odors, pets, cooking, and light VOCs. Choose Vocarb if you're dealing with heavier chemicals, formaldehyde, fresh paint or flooring, or ongoing fumes, since it's tuned for those gases. When in doubt, email us about your space and we'll help you decide.
Do I need the UV-C lamp?
For most homes, no. The Pro 5 HD does its real work through the carbon and Super HEPA filters, and those handle particles, odors, and chemicals on their own. The optional 10-watt UV-C lamp adds a supplementary layer of germicidal treatment if you specifically want it, but it isn't required for the unit to filter effectively.
How loud is it?
The Pro 5 HD 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 to balance airflow and sound.
How much power does it use, and can I leave it on all the time?
Yes, it's built to run 24/7, which is how AllerAir recommends using it. The Pro 5 HD draws 1.3 amps at 115 volts on high, and less than that on the lower speeds you'll use most of the time. Running it continuously on low is the simplest way to keep air quality steady without a noticeable jump in your power bill.
Does the Pro 5 HD produce ozone?
No. The Pro 5 HD cleans air by filtration: a pre-filter, a deep activated-carbon bed, and Super HEPA. There's no ionizer and no ozone-generating process. The optional UV-C germicidal lamp doesn't generate ozone either, which is what you want in a unit built for sensitive users and continuous use.
Where do I get replacement filters?
Genuine AllerAir replacement filters for the Pro 5 HD are available here at Pure Indoor Living. The pre-filter changes every 2 to 3 months, the Super HEPA every 1 to 2 years, and the carbon filter every 2 to 3 years depending on how hard the unit works.
What's the warranty?
The Pro 5 HD 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 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.
