Honeywell 18155 SilentComfort Permanent, True HEPA Air Purifier

First off - my husband and I smoke and have 2 dogs in the house. We put one in our kitchen, one in our great room and one in our master bedroom. We notices a difference in a couple of hours after we turned them on! We even bought 2 for my mother in-law and they have helped her asthma! They are not too loud that you can't sleep and after a while you don't notice the noise at all! Great Purifier!!!!! Buy Honeywell 18155 SilentComfort Permanent, True HEPA Air Purifier!

Honeywell HHT-011 Tabletop Air Purifier with Permanent HEPA Filter

I'm giving this air filter a rating of 4 and not of 5 simply because I don't know what kind of miraculous feats are obtainable with such a machine having never owned one before.

My husband and I purchased 2 of these after discovering that he and our oldest daughter were allergic to our 4 (indoor) cats. We keep one in our room and one in the girls room. Thus far, I have noticed that the whole house (less than 1000 sq. ft.) smells nicer, and my husband and daughter do seem to be sleeping better. Our daughter has asthma and has not needed her inhaler since we have had these filters. Could be the filter, could also be the change in medication... Could be both!

I crank up all the settings during the day and then turn it way down at night. It is a little noisy in my small house with both filters turned up during the day, but at night on the lowest settings we all sleep fine and what little bit of noise there is seems comforting.

The filters are easy to clean. The machine was easy to snap together and the instructions for use were clear. All in all, I'd say it was completely worth the money put into it and perhaps I will invest in one to sit in my office as well, due to the proximity to the litter box...Buy Honeywell HHT-011 Tabletop Air Purifier with Permanent HEPA Filter!

Honeywell 50250 99.97% Pure HEPA Round Air Purifier

I have severe year-round nasal allergies. To make matters worse, my prolonged allergy symptoms have triggered the growth of polyps in my nasal passages. Zyrtec and other allergy medications offer only partial relief. Then, I stumbled on this very favorably rated air purifier and decided to get it to see if it would help with my allergies. I have been using it for 6 months now, and the difference it has made is simply remarkable!

- HEPA Filter (High Efficiency Particulate Air filter)
I use the Honeywell HEPA Air Purifier in my bedroom, which measures about 15' x 13' - well within the specification of 17' x 22' for the optimal performance of the air purifier. I keep it turned on 24-7.

Initially, I wasn't entirely sure if this HEPA business wasn't mere hokum. But much to my delight, this air purifier has made a HUGE difference for me. My allergies symptoms have consistently shown a marked improvement whenever I'm in my room with my air purifier running; sometimes my allergies don't even act up - What a relief! I also don't get sinus headaches as often as I used to. Finally! Respite from the barrage of outdoor allergens! To all the allergy sufferers: the Honeywell HEPA Air Purifier does work!

Now, the *CAVEAT*
I have discovered that the air purifier works in alleviating my allergy symptoms only at the highest setting. It really moves the air in the room at the highest setting, but the problem, as many reviewers have noted, is that it can be quite loud at the highest setting. I think this is inevitable since the noise comes NOT from the fan, but from "the high air flow", as someone has astutely noted.

The noise really doesn't bother me too much. As a matter of fact, it serves as white noise for helping to mask my tinnitus. The only time I turn it down is when I need to talk on the phone.

- Carbon Filter
The carbon filter is very effective at controlling bad odors. The recommended carbon filter change interval is every 3-4 months, which sounds about right since my filter started losing its effectiveness after roughly the same time period. If you don't have a problem with bad odors, you can probably change the carbon filter much less frequently.

Contrary to some opinions about the aesthetics of the Honeywell HEPA Air Purifier, I actually think the unit looks rather attractive. But, of course, it's a subjective matter.

At the lowest setting, the unit wobbles a little, which makes me worry about its durability. However, I've had my Honeywell HEPA Air Purifier for six months now, and I leave it on 24-7 -- no problems so far. At any rate, the unit has a 5-year warranty (a rarity these days).

I just wanted to share my personal experience with the Honeywell HEPA Air Purifier since it's worked so well for me. Hopefully, it's been helpful for you. Do be aware of the noise issue that many people have trouble with. Good luck.

Honeywell 38002 Enviracare Universal Replacement Pre-Filter

My Hepa filter was great when I first purchased it. It made the air smell clean, but more importantly, it reduced my allergies to household dust.

However, it has not been the same since I replaced the filter it came with, and put this pre-filter on it. This pre-filter smells really horrible. It makes me feel sick. I can't even describe the smell exactly. My husband thought it smelled like chemicals, but I thought it smelled like rotting meat. So, needless to say, I haven't been using my Hepa filter lately.

I'm going to have to research other filter options.Buy Honeywell 38002 Enviracare Universal Replacement Pre-Filter!
