Rated 5 out of 5 by from Great product for desk and great price! Hi. This is a great product that helps me with my allergies at my desk at work. I have always had allergy flare ups in my current workplace office. After getting this product, it feels like I can breath so much better and don't have as many allergy flare ups at my desk. I have it at my desk right beside me, and on any of the settings it is not too loud or bother me or my coworkers. I tend to keep it on the lowest or second lowest fan speed setting. I don't use the ionizer very often. I also like the aer1 true-hepa replacement filter. Thanks for making great products that anyone can afford!

Rated 3 out of 5 by from Works ok I have bought two at the same time and started using mines about one 1/2 months ago and i have noticed a difference but i still need to get maybe 6 more cause i have big apt. I have dirty air ducts from my landlord not wanting to clean them . I first saw these on amazon and and bought them there and so these desktop purifier seems to help . I how ever been having runny nose these past few days so i either need to get air ducts cleaned out or keep buying these for ever room . If anyone one or company have advise on what i need to do far as my air ducts need to be clean let me know cause i do not feel i have to clean them out cause i do not own this house.

Rated 1 out of 5 by from I have the older model Bought the model before this one I believe HAP9240. I consistently cleaned the unit and changed the filter each month with the green quality AER HEPA filters. I thought it was working well until I shined a flashlight down the outlet side of the unit, (where the fresh "purified" air is coming out of) and it was filthy. Yes I have the filter in right and yes it has a good seal. I know it's a cheap purifier but I wasn't expecting that amount of dirt and particles on the fresh air side of it. I enjoy Holmes products and I'd like to see Holmes make this right and correct it.

Rated 5 out of 5 by from Stops nearby dust and smoke pronto Positioning this small air purifier is critical. I have one over the cat litter boxes in our RV. I use non perfumed litter so dust smell is my enemy. I have asthma and allergies. This air cleaner with the ionizer on works so well that we hardly notice the litter boxes. I also add a large hepa at night during high pollen. My daughter uses hers at night near the bed. It cleans and creates white noise. She is an LPN and adores her air cleaner and her sleep. Our third 242 is near the computer in the guest room at our cottage. Great for cleaner smells and white noise. This room has carpet and tends to have an odor that I can smell. Not so with the ionizer on.

Rated 5 out of 5 by from They last forever I bought this to replace one I had for 45 years. It was still working but when I saw this one on sale. Well it was a sale. I once tried another company that had a TV commercial showing how quickly it removed air pollutants. Well it blew up and caught fire in less then 30 days. From then on I will only buy Holmes products and you should too

Rated 3 out of 5 by from Cleans well, but is rather loud I have had mine for some years now, and just looking at the old filters tell you it cleans well. BUT, it is so darn LOUD! I have always slept with a purifier running because I can't sleep with it too quiet. But this machine is right on that too-loud threshold. Granted, it is in a very small room, but my older machines had a more reasonable volume. Another downside is I can't figure out how to take the case apart for a good deep cleaning. Older styles were very easy. I had to borrow someone's air compressor to get all the dust blown out of it, which was making it even louder. So, if you want a machine that filters well, this one will make you happy. If you need to sleep with White Noise, this will also help, but it may be a bit too loud for you if you have it in a small room.
