What can I say. My neighbor ( = David Pascale = 5-star review from 7/10/2024) showed us his 2 R414 units, giving us an "in-person" demonstration. We were so impressed with his Air Purifiers that we promptly ordered our R400 unit. The device is compact — easy-to-set-up — and "hums" quietly on low speed. We completely agree with David's enthusiastic review! P.S. The web site is easy to navigate — and very helpful in understanding the pros and cons of the various devices. Thank you!

Love it

Use the R-600 in my 3D printing shop. The charcoal filter absorbs the smell from the ABS filament. Leave it on low at all times and no smell in the 800 sq ft room with 5 printers going.
Use the R-700 in the house. Centrally located and leave it on low but will turn it up if we cook something and want to quickly clear the air.
The advantage to these is that there is a lot of charcoal.

We have a wood burning stove at our house and whenever we open the door to the stove to get the fire started or add wood, the air quality in our home goes down a lot and there are a lot of VOC’s and particulates. Whenever this happens, we turn the air pura on high and usually within a few minutes it gets our air back down into the good / great range. I am so grateful to have this air purifier!

This air purifier has been very helpful. I purchased it because I have mold and dust mite allergies. I initially had an issue with the UV 600 having a slightly annoying noise. The company took care of this by allowing me to upgrade to the UV700 by just paying the difference. Great company. I have a special fondness for Canadian built products

I called Allergy Buyers Club because we have a mold problem that we are in the process of remediation. However, until remediation is completed, we wanted to run air purifiers to help diminish the mold spores. I had no idea what I needed. Luckily Tony answered the phone and spent a considerable amount of time answering all my questions and advising me on which purifier would be best for our situation. I can't express how appreciative I am for his expert guidance. The purifiers came and just like he said, they are high quality, quiet and so easy to operate. We can already tell the air seems "fresher" throughout the house. Most importantly, we feel our house is now safer for our daughter and will aid in purifying the air until remediation can be completed.

None come to mind. Has a leg up on other machines in a number of ways. 420 cubic feet per minute delivered on max makes the R600 part of a small group of air purifiers which move significant amounts of air. This machine certainly appears less challenged than my IQAir Health Pro, which nervously cranks out 240 CFM. On high, my R600 is calm, all the while moving 180 CFM more. Quality construction and a focus on reducing vibration make it deceptively quiet. It's obviously made to last. It is a solid, sealed, and durable appliance. The high quality blower is wisely placed on top, pulling air through the filters rather than pushing. Cylindrical filters increase surface area while decreasing the velocity of air entering the machine. This improves filtering efficiency and lowers particle penetration. Perhaps best of all, the carbon is refillable. Air Pura can afford to offer an incredible warranty because the blowers just never burn out. The operating costs for this machine are low, regardless of what you have read. Hepa filter replacements every 3 years or so, washable prefilters and refillable carbon. Uses about half the amount of electricity of the machine which I see as its logical competitor, the IQAir Health Pro. In a market flooded with emotional appeals, Air Pura places function over form. The R600 is an air purifying appliance, rather than just a device. I consider this to be the best portable air purifier, based upon its capability and cost efficiency.

It had laminate floors and a supposedly zero-VOC paint that bothered my chemical sensitivities and perhaps mild mildew smell. This beast did the trick.

We bought our R600 when I was recovering from mold illness in 2016. Since we lost much of what we owed (and insurance didn't help replace), we were short on money and bought this basic model. Never regretted that decision and plan on buying a second R600 soon for our second floor!!
When I was recovering, we rolled it from room to room in our 1000 sq ft home, and it kept our air clean enough to help me heal. Because it is so well made, it had no problem with our cross-country move (we took the wheels off and of course packed it well). We used to run it 24/7, but now that I'm better, we run it at night or when needed. It quickly takes care of kitchen smoke, pet smells, cat litter dust, and allergens beautifully! You can smell a difference.
Cons: On the highest setting, it is loud. You need to keep track of when to change the filters and changing the filters is cumbersome. It's difficult to clean the interior fan portion as dust can build up there. But none of these things diminish this unit in our opinion as we like that it has one job and does that job really well. We love it!!!

I've had the r600 for several years and run it constantly. It removes cooking and chemical odors quickly. I feel better having this unit.

Bought the R600-H back in 2009. Purpose was to filter the air in an unfinished basement with exposed pink insulation across the whole ceiling. There's about 600 square feet of space with an 8-foot ceiling. The unit has been running 24x7 since I bought it. Never, ever had a problem with it. AND, within the first day, the particulates I could see in the basement air (when the light was just right) were gone.
Since purchase, refreshed the filter pack, but that's it. Unit does the job with the kind of product reliability you rarely find these days.

I purchased this product due to having constant allergies, sinus infections, and having many pets in the house. It has exceeded my expectations and I'll be getting another for upstairs as soon as I can! My allergies are all but gone and I haven't had a sinus infection in months! It also knocks down the animal odor big time! Great product!!!

I recently added it to my Austin Family, which consists of three Juniors, one IT and the newly added Immunity Machine!

This is our 3rd one and the timing couldn’t be more perfect. My husband just tested positive for the flu so we have one going in each room as we sleep separately and one in a central area.

That fact that I only have to replace filters every 5 years is far better for me to keep up with than every 6 months. Also. We use it nightly on high as a while noise machine. It’s amazing. Very satisfied and repeat customer.

Oh. And we had one small shipping issue with this one and not only clumps I speak with someone on the phone but then the follow up via email was incredible customer service. They stand behindand support their machines!

We put this in our basement as we have a young daughter sleeping in a finished area and wanted to make sure the air was okay. Turns out we had a radon problem and close to a co2 issue. This alerted us to these issues, which lead to a radon vent being installed. Our CO2 is great, our Radon is gone and everything else looks good! I got it to detect mold and only slightly curious about the Radon. Glad we sprung for the higher model. If you care about Radon and don't want to spend as much, their batter powered sensor they sell here and at HD works great, we used it at our MIL and it matched up with the pro reading. This airthings Plus also matched the professional Radon sensors.
