This is an air purifier for a 250 sq, ft. room. It is not a carbon filter. This is perfect for people with allergies etc.

The V5 filter is included in the Plus model. The V5 removes gas and odors (http://www.iqair.com/home-air-purifiers/healthproseries/features). If you don't care about that, you could purchase a non-plus edition, however, amazon doesn't seem to carry this model. The following website has all the models with their tech specs for comparison: http://www.iqair.com/home-air-purifiers/healthproseries/tech-specs

It's for one filter but it can last a long time, depends on its use and where you have it. I have had other air purifiers, less expensive, and did not have the same relief as I do with the IQ air, so the price has been worth it.

The multiple-stage filtering system, the life of the motor, the amount of air the purifier can move and filter at once, the noise level. There are many reasons this purifier costs more initially than Miami of the others available here. As someone who needs a purifier in each room for a child with severe medical complications, I've done the searching, I've purchased many, many inferior air purifiers, and without a doubt, the Alen Breathesmart is far and away the most effective. I also have two RabbitAirs for the bedrooms because of their quality, size and noise level, but I will never go back to, or reccomend any lesser air purifier. I suggest looking at consumer reports and getting more detailed input, but the money you spend on a high quality filter makes it more than worth the investment in its longevity and consistently clean air.

I believe the difference is the level of filtration. I use the ez4 b/c It filters out more and smaller contaminant particles

The old IQ Air GC MultiGas does not remove odors. I can't speak to the newer model, but I suspect its no better.

Hi! I'm not sure, because I bought this filter for the Hamilton Beach True Air Odor Eliminator plug-in pet air purifier. If you look at the picture of thisfilter replacement product and see the purifier that is encircled, that is what I have. I have never used the 3 stand-up products that are also pictured on this filter replacement box. Sorry, but at least least you know which product I have used with this filter. It's a good filter. No one can tell I have a cat in my house. Hope this info helps!

The filter requirements is a bit confusing. Three HEPA filters and three carbon filters are required for the larger room model # HAP756-U which I recently purchased and currently using. (Two of both the HEPA and carbon filters are required for the smaller room unit HAP726) Three true HEPA filters were included with the my unit and already installed (there are no discernible marking on the installed filters I can detect indicating a filter model number). However, there were no carbon filters installed or included with my purchased unit but I did purchase a pack of 4 which I installed when I set up my unit. I purchased a package of 2 Holmes make HEPA replacement filters (HAPF600D - B Filters) at the same time. Had I researched this better, I would have purchased the same box of 2 filters, plus 1 lone filter (same model #) since the unit requires that all three filter be changed when the red light indicates the filters be replaced. I am not aware of any distinction between an HAPF600 and an HAPF600D filter and I couldn't find this out on the Holmes website, either. Perhaps (but not sure) the "D" version removes either different allergens or more allergens from the air. As far as the "B" designation, I believe this identifies these as HEPA filters versus the "C" designation applied to the carbon filters.

I don't smoke, but I think both models are good for removing the odor. The 9500 will cover a larger area and that would be the only difference.

I believe the KC-860U also has a humidifier function whereas the FPA is just an air purifier..

The 3800 is more powerfull and generates more heat. I recommend the 3800 with no doubt.

The 02 does 160 sq/ft room the o3 does 360 sq/ft room. Mine lasted less than 2 years, the electronics burned out and cannot be repaired as parts are not available even from 3M. With the cost of the unit so high and also the filters I would look for a less expensive unit that also uses Hepa filters. I bought a replacement that costs half as much and uses an equal quality filter.

It'll save you money from the Honeywell in a couple of years b/c the filters need less changing and it uses much less electricity. It's also quieter and has an air-freshening ionizer that the Honeywell doesn't, in addition to the HEPA.

It's much better. I have both the Alen Breathesmart and a Winix 9500. The Alen is quieter, has greater square foot coverage, and removes allergens more completely.

I have a pretty loud air-purifier and computer as well, and the AT2020 does a good job of not picking up those ambient noises quite well! Most of my recordings are whisper quiet in the background. Hope this helps!

This is a wonderful purifier...It is still whisper quiet after 18month...You will eventually need to buy the prefilter...I use cut to fit I purchased on this site...they work just as well...My hepa filter lasted almost a year before needing replacement...I vacuum it out once a week...You will love this unit...
