Question: Has anyone found a new filter for this 'permanent filter' unit?
Document: I bought this for my room to help with dust control and maintain fresh air, which it did for about 3 months. After that, all performance was lost. No matter how many times I cleaned it according to the instructions, the unit never worked as well as it did new. The selling point of this product is the "permanent filter" which supposedly only requires the user to simply vacuum the filter and it will work as well as it did new.
I have noticed there is a small dust ring just around the base but with it keeping the whole room less dusty for a week that is nothing. I don't mind dusting once a week. I would recommend this to anyone with a smaller room. Should the unit fail too early I will as always come back and give you an update.
The Holmes HAP600-U is an unusual looking air purifier that can easily be mistaken for a high tech speaker or an art piece. It has a HEPA (High Efficiency Particulate Arresting) type filter to efficiently trap dust particles and tiny pollutants in the air. What I really like is that the filter is permanent, so I do not need to buy new ones from time to time.All that's required is regular vacuuming the filter itself.
Upon removing the filter, the unit will push a lot of air but that defeats the purpose of the product if you use it without the filter. The permanent filter cannot be cleaned with any liquids of any sort, not even water, you can only vacuum it. Holmes does not sell a replacement filter at all, which means I am stuck with an egg shaped fan with a black light at the bottom that I paid a lot for...
Then back to speed one. My room smells fresh and looks clean. I am not coughing as much if I sleep with the window open so I know it is working. I have had so many air purifiers over the years and always hate the expensive filters that have to be replaced. This has a permanent filter so no more cost after the unit is purchased. My room is 12 by 16 feet and it handles the room size well.
Some reviews have indicated that the filter has been discontinued for this product - the filter on this product is actually a permanent filter - if you clean the filter and the yellow check filter light remains on.... Holmes customer service indicated that the light needs to be reset - in order to do this press down on the check filter light and hold while counting to 15 - release button and light should have turned off and unit be ready to go.Regarding actual product - have had for approx.
Because of this I wouldn't place the unit on a rug and the clean air coming out does not create a fan like breeze which might be uncomfortable in the cooler weather. After two weeks of use in a small room that I thought was very clean and dust free there was noticeable accumulation in the filter. It was easy to remove the filter and vacuum clean.The air cleaner feels substantial and heavy for its size and the fact that it is made of plastic. It would not easily tip over.
This is a nice little 3-speed HEPA filter with ionizer for rooms up to 120 square feet (10' x 12'). I've had no problems with this unit in the first month I've owned it. It's a bit louder than other HEPA air filters I've owned by Honeywell and other companies, but I use mine in the bedroom, and I like the fan noise &#8211; it functions like a white noise machine.I like the attempt at an interesting design.
I am hoping it holds up to cleaning and works just as good as new!
I imagine it is more useful to prevent you from tripping over it in the middle of the night.I would definitely recommend this air purifier to anyone in the market for one.
Answer: This unit is pure garbage and I ended up tossing out the entire thing because after just a couple months of use it hardly worked at all regardless of how many times I "cleaned" the air filter. The instructions explicitly say do not wash the filter in any way other than using a vacuum which does nothing. 100% garbage, do not buy if you are reading this, it is total junk after 3 months with odors and minimal air flow from unit. Waste of money because it is a "permanent" filter with no replacement options. Look elsewhere for something better, don't waste your time or money.
