5.0 out of 5 stars Works Great for Indoor Allergy Sufferers, August 10, 2009

This review is from: Holmes HAP424-U Air Purifier (Kitchen)

I'll start by saying I have pretty bad indoor allergies. I just moved into an apartment about two weeks ago and after the first night, I woke up the next morning feeling terrible. I thought I was just coming down with a bit of a head cold. After only 48 hours after moving in, I noticed the intake fan filters on my computer (custom built by yours truly) were clogged with loads of dust. Normally the filters need to be washed around once per month, not every two days. I wasn't getting sick, it was the ridiculous amount of dust in the air that was screwing with my lungs and sinuses. The carpet in the bedroom had been poorly maintained and didn't look like it had seen a vacuum cleaner in more than a year. If I could have my way I would pull it up and install some linoleum, tile or hard wood to ease my allergies. Since I'm just renting, I had to get creative. I vacuumed the carpet thoroughly and over the course of several days, scrubbed the carpet with a steam cleaning machine. Most folks with a weak stomach would have hurled if they had seen what was floating around in that black dirty water I poured out afterward. Even after all that, there was a tremendous amount of dust in the air. I could turn on my 3 watt LED flashlight and see all of the particulate floating through the air. Late one Saturday night, I wandered into my local Wal-M**t and snatched up this air purifier.

Lo and behold! I found something that works! This little slice of heaven moves a ton of air and I don't necessarily consider it to be noisy. I'm used to the white noise my PC makes to begin with and sleep with a fan running so it doesn't bother me at all. I would say it's about as loud as your standard box fan on a medium or low setting. It's comforting to know this machine is chewing through enough air and making a difference in the level of dust in the room. I shut my bedroom door and turned the little unit on "high" and let it go to work. Within two hours there was a noticeable difference in the air and I could no longer see bits of particulate floating through the air with my flashlight.

The price of the proprietary filters isn't going to be a problem. I already felt like I was keeping Pfizer (makers of the OTC allergy medicine "Zyrtec") and the Halls cough drop company in business up to this point so in the long run I'll probably end up saving a few bucks. I'm not sure why some people are having trouble attaching and detaching the rear grill. Unless you're a handicapped mongoloid invalid with Parkinson's, it's a pretty straight forward process.

I'll have to do a little bit more research on the "ionizer" feature. The instructions claim it's safe, but I know better. I'm not entirely sure it's healthy to inhale electrically charged molecules that are blowing past my head all night.

Either way, I'm waking up in the morning feeling great instead of coughing up a lung! I also ordered a 3M Filtrete filter for my central air conditioner. I'm hoping it complements this purifier.

My allergies haven't gone away completely, but having this unit around makes a huge difference. It might not work for everyone, but I'm happy with it.

5.0 out of 5 stars Hepa for the rest of us, March 1, 2009

I think this is a good air cleaner at a reasonable #.

+ Small footprint (about 10.5" across) vs the typical 14-18" units
+ highly directional (swivel 80 degrees)
+ simple controls, it even has a remote for across the room use
+ Quiet volume (except on HIGH)
+ Easy access to the filters (x2)
+ Static discharge (negative ion) feature

- The aircraft designed fins are difficult to clean (after a while)
- Expensive proprietary filters (they all are but still???)

The unit has a door which swings open from the rear, to provide access to the 2 (included) filters. The filters are on grooved tracks; which when moved 3/8 of an inch slide out. The exterior most barrier can be vacuumed gently. This is for medium rooms (rated up to 12' x 16').

2.0 out of 5 stars Headache!, September 11, 2008

Don't buy Holmes® HEPA type Tower Air Purifier - HAP422B-U. The only virtues are superficial: the towers look elegant and take up little space. And OK in the summer it acts as a cooling fan. I don't know that it does any more than a fan.

However it came with little instructions, with no pictures, diagrams or any real explanations. Right now I am scouring the net for an 800 number. The filter is almost impossible to change. The door has to be forced open to near breaking; and while you're lining it up to close it back, three of the items keep slipping out of place. Putting it on the floor to do this doesn't help because it rolls around. I'm still not sure the door is completely shut.

I can't find any numbers to call, no online instructions, and I can't get the red change filter light to turn off now that I've changed the filter. The ion light is cool but there's no instructions as to when and how to use it.

The production must have been outsourced to China, and no translaters were hired.
