Age 18-24 25-34 35-44 45-54 55-64 65 and older Gender Male Female Verified purchaser We live in urban NYC, beside the Brooklyn Bridge; Air quality is severely polluted. Before buying this filter I needed several breathing treatments daily w/a nebulizer. After a month of having it run full blast, I'm off all breathing treatments and happily recovering from pneumonia. The machine arrived well packaged, very easy to set up... No problems with the filter door (it clips and stays shut). Within two weeks I noticed the buildup of both course and fine debris. Set on level 4 (highest setting), the white-noise output fades into the background. Far as square footage, this machine is cleaning about 500sqft. and doing the job very well. I pay .18+ per kWh for electric; Running full blast 24/7 my bill is up about $20.00 (less than a movie ticket and dinner out). I can recommend this machine 100%. Added benefit: My tacky-cardia due to nebulizer treatments has stopped. This filter has improved air quality immensely, and in my opinion it's been life saving.

Verified purchaser I have allergies and COPD, and this has been a great investment. I leave it running constantly on 3. It moves quite a bit of air so it does make a little noise, but nothing I find objectionable. After all, you got to move the air to clean the air, and it definitely makes a difference in the quality of air that you breathe. I can find the replacement filters locally at a popular big box store, or catch them on sale online at the Holme's website and stock up. Design wise, it's a very simple but effective device. sharp air purifier fp-p30uThere is not much there to go wrong reliability wise... it's a fan, some filters and a control board, and that's about it. homedics air purifier ar20 manualParts that aren't there can't fail I used to be a serviceman for a major catalog based retailer when I was still just a pup. akos air purifier

This cleaner works better and more reliably than many I've seen and worked on that cost several times the price. Length of ownership: over a year Be realistic, don't try to run it on setting 1 and expect it to do much. Verified purchaser I used smaller units, but this is just right for larger room. Verified purchaser Verified purchaser My cough and my husbands sneezing and congestion have subsided. The common house odors are gone. It works very well. Our kitchen and living room are conjoined with the living room ceiling being a cathedral. Its more than 450 sq ft. That says alot to me. I have ordered another for our bedroom, I'm all about clean air.

I am especially pleased with the customer service received when I had a problem with the first purifier shipped.

I originally purchased from someone other than Holmes, but the motor made a ticking noise and I tried to return to the store but they would not take back. So I called Holmes and explained my problem the only two question they asked me what was the code on the plug and my shipping address. Within a few days I received the replacement unit and for me to dispose of the other unit. that was over 5+ years ago and it has run 24/7 since. My wife had always suffered with sinus problems in the spring and fall since purchasing and running it all the time she has no problems. Another benefit our place has a lot less dust as we do not have to dust as often. You can spend a lot more money but this unit does the job and is rated good by consumers report. for our family we do our filter purchases etc from Holmes you can not beat the customer service or the quality of the product Verified purchaser I bought both a large and medium air purifier and I am so glad I did. My son and I both have allergies.

With the horribly high pollen season, we have not had any allergy symptoms since using them in our apartment. I also love how it filters out kitchen Odets. I've been in my new apartment two months and the new installed carpet still smells new. I'm really happy we can sleep with the windows open on cool nights. Cons: while on high level setting its a little noisy . However at night the sleep setting is similar to a quiet fan Verified purchaser Verified purchaser My husband and I purchased several of these air purifiers and were very happy with them. Recently we bought three more, two of the large air purifiers and one small one. The really work well to make our home fresh and comfortable again. We sleep better and feel better! One more thing the dog sleeps better too! We are very pleased with the purchase of the air purifiers. Verified purchaser Verified purchaser We bought this about a month ago and have already seen a difference as well as felt our allergies get significantly better.
