No I don't think it's a hepa filter, but the reviews of this purifier are very good. I'm on my third, as it doesn't seem to really be effective after 6 months. However, I am very allergic to book dust and mold, and this filter has been very, very good at taking away dust and spores. Unfortunately, I have to use a lot of books at work, and this machine is really helpful.

No, it is not a true hepa filter. I wouldnt recommend it as it was not well made and also mine did not come with the car charger. I returned it.

These are not true HEPA filters; they are HEPA-type filters. True HEPA filters are available at http://www.amazon.com/Holmes-HAPF30D-Replacement-HEPA-Filter/dp/B0045LQCIO.

Yes they are HEPA filters. However, I've had allergic reactions using the 3M mask with these filters, and I don't think I would if the mask were truly removing 99.97% of the allergen. Some allergens leak through, somehow. These filters are the best I know of to filter out allergens, but I've had many allergic reactions to animal dander right through the filter. And to some kinds of mold. Either the filter itself isn't very good at filtering out some allergens, or other parts of the mask leak somewhat.

It says that the exhaust filter is a hepa filter. There are also two types of bags that you can get - one is a little more expensive and more like cloth than paper and I think this also helps retain tiny particles.

Yes. I used to live with a heavy smoker and had a Honeywell HEPA filter system at the time. As long as you are on top of replacing filters it makes a huge difference.

No the HEPA filters are made to be replaced. HEPA filters are the best designed filters to clean even microscopic particles out of the air but are not made to be washed.

No. The HEPA filter is a cylindrical core at the middle of the cyclone, which may be removed for washing.

I'm pretty sure the pre-filter and hepa filter are together. The pre-filter is at the front and the hepa is at the back.

Neither. It's just a straight HEPA filter. Air is sucked through the filter and out the other side.

The HEPA filter is washable. I soak it in a small container (or sink) with a squirt of dish washing liquid for 15-20 minutes, swishing occasionally then rinse well doing same method. It must be completely dry (overnight near fan or heat vent) before use. I own two HEPAs so one is always clean and dry. You should clean the HEPA filter about every 3-4 months depending on how frequently you vacuum and how dirty the jobs are.

No, it has a synthetic fiber pad that sits underneath the bag chamber and that's it, if you want hepa filtering, look for a vacuum that states it clearly in the description, also I found the bags do not seal adequately and as such a lot of dust goes past the bag opening and gets sort of trapped in the synthetic mesh pad I described earlier.

Yes, the HEPA filter is completely washable -- but it would have to be replaced after several washings to insure maximum air flow. Before washing the filter, it should be VACUUMED thoroughly FROM THE DIRTY SIDE before WASHING FROM THE CLEAN SIDE. This method has allowed the HEPA filter to be fully functional after over a year of service. Good Luck !

No. It has 3 large hepa filters that last longer than other units I've used. I like the size and price of this unit. It moves a lot of air and is a bit loud. Not a drawback for me. I need background noise to distract me from my tinnitus.

The carbon filter is a thin spongy filter and the HEPA filter is larger made of a paper type material and pleated. I vacuum both filters to clean them and actually rinse the carbon filter with water and hang to dry being careful to wait until it is fully dry before using

Please pardon my ignorance but I'm not sure what "EF" means in reference to a Hepa filter. I can tell you that I cannot detect any dust escaping through this filter after several uses and that, for me, qualifies this filter as a resounding success.

I cannot say it is a "true" HEPA filter but my son has terrible "environmental" allergy and the 726 helped a lot. We used it in his bedroom and moved it to his dorm room when he started college. The filter helped him while he is in school and I was very surprised to see how much dust collected on the carbon filters (C) and the "B" filters. We brought two new set for him to bring to school this year.
