Tools and Hardware Reviews of Holmes® HAP412N-U HEPA-Type Mini Tower Air PurifierCustomer Review: Great air filter to start out with Summary: 5 Stars
This is the first air filter I've ever bought. After using it for 6 months, I can now testify on behalf of this product.
I've been using it in my bedroom (dimensions 16x12 ft) continuously on the middle setting. The noise level is minimal on the 2nd setting (sort of like a low hum... I don't even notice it anymore) and even quieter on the lowest setting. I have pretty severe dust allergies and even the first day, I noticed a difference. No more sneezing, stuffy nose, itchy throat, etc.
The recommendation that came with the manual said to change the HEPA-type filter every 3-4 months. After about 4 months, I opened up the unit to check on the filters. There's a washable carbon pre-filter and a replaceable HEPA-type filter. I cleaned the pre-filter. The HEPA-type filter looked pretty much like new, so I didn't buy a new filter. (there are pictures of how dirty the filter looks at various stages inside the panel after you open it up).
Last weekend, I had to go out of town to take an exam. I arranged to stay with a friend. He warned me that he had recently gotten some cats. I'm also highly allergic to cats. I loaded up on allergy medicines the weeks prior to the trip (nasal corticosteroid sprays, antihistamines) and thought that would keep me from reacting to the cats. As a last minute idea, I brought this little air filter with me as backup. And boy was I glad I did. After an hour at his apt, I started sneezing non-stop and feeling altogether miserable. I whipped out the air filter, and set it up in the bedroom. After retreating to the filtered room, my symptoms subsided and I woke up allergy-free.
I see some other reviewer complaining that there is a layer of black dust/sooty material that accumulates around the filter if you have the ionizer on. The accumulation is supposedly heavier if you smoke in the house. I'm not a smoker but I still notice a thin layer of black dust around the filter. It doesn't bother me at all. You can just wipe it away with a damp paper towel (if you are on hardwood) or vacuum it up (if you're on carpet). I'd much rather have the black dust particles on the floor rather than floating around in the air where I am breathing it in. Of course, if it bothers you, you can always turn off the ionizer function and just use it as a filter.
Lastly, I see some people complaining about the cost of the replacement filters. It comes out to be about $18 each if you buy from Amazon. That's not so bad ... I looked at some other brands and they're still in the teens or $20's. Some other reviewer suggested vacuuming the replacement filter so it lasts longer. This is what you would do with a permanent HEPA filter anyway, so it didn't sound like a bad idea. Today, I opened up the filter again and saw that the HEPA-type filter was covered with cat hair. :-( That was just with 2 days of continuous use at my friend's apt. So perhaps the filter would get dirty much quicker in a household with pets that shed a lot.
I went ahead and vacuumed the HEPA-type filter on this unit... it cleared the filter without sending much if any dust in the air. I figure I'll change the filter once a year at this rate.
I'm completely allergy free in my bedroom. However, I still sneeze in the dining room area. I'm now saving up to get an air filter for the dining room / living room area. Please let me know if you have any suggestions on bigger air filters.
In summary:
This little unit is affordable, portable, and effective. I highly recommend this to anyone looking to get a good starter air filter for his/her bedroom and doesn't want to spend over $100 for something bigger/fancier just yet.
