How many filters, at once, does this unit use? I would assume 1 HEPA filter (HAPF600D-U2) and 1 carbon pre-filter (HAPF60)?

This unit uses 3 hepa filters, which come with it new, and 1 pre-filter also included. If you buy replacement hepa filters on Amazon look for the 2 pack. It's barely more than the single filter price.

It takes three (3) each. The HEPA filter is the expensive one and I replace it about once a year, while the carbon filter is replaced every 3 months. When you replace the carbon filter you'll be able to inspect the HEPA filter. I have washed the carbon filters and re used them.Keith

It comes with 2 filters, one is paper hepa. The other is charcoal. Life of filters, should be 3 months for charcoal, 1 year for paper. I have owned unit about 2 months. There are filter lights to indicate when filters need to be changed. I am happy with the unit so far.

Hello, the unit can use up to 4 filters at a time, each one has a life of 3,000 gallons, I hope I helped you, have a nice day.

The box holds two filters. Just like the picture shows. The MACHINE uses two filters at the same time to cover the entire area of the filtering surface. So it takes two of these filters at a time, side by side. That said please use the Carbon Filters as well as it will make these filters last MUCH longer. The carbon ones are much cheaper and they still remove much of the larger dust particles that really clog the filter and kill its effectiveness. Short answer. Buy 1 box at $24 to replace the filters the machine holds (assuming you have the same machine as me I presume they have smaller machines that use only one)- Hope that helps.

There are 3 filters. A foam pres filter, a middle filter that claims it breaks up VOCs and a HEPA filter. It works well for us.

It comes with 2 filters. One activated charcoal filter and a hepa filter. Replacement filters are expensive. About $80 for both filters. However, the filters last two years. It is very easy to add a third cut to fit charcoal mat pre-filter in front of the activated charcoal filter. I do this and replace it every four months to preserve the original filters. It's a very nice air filter. Quiet and energy efficient.

The unit includes one HEPA and one carbon filter. I ordered the additional filters for replacements. The carbon filter should be replaced after three months of continuous use, and the HEPA should be replaced after 12 months of continuous use. Note: The front panel has lights to indicate when a filter is due to be replaced. It glows yellow for a several weeks then changes to red, so you get plenty of advance notice that a new filter is due.

According to the schematics for that machine there are two filters. The HEPA filter is 4.99. I can sell the both of them for 6.99. Please feel free to call me at 5713225005.

Sure do Michael...the pre-filter is model HRF-B2 and the hepa filter is model HRF-H2

The filter requirements is a bit confusing. Three HEPA filters and three carbon filters are required for the larger room model # HAP756-U which I recently purchased and currently using. (Two of both the HEPA and carbon filters are required for the smaller room unit HAP726) Three true HEPA filters were included with the my unit and already installed (there are no discernible marking on the installed filters I can detect indicating a filter model number). However, there were no carbon filters installed or included with my purchased unit but I did purchase a pack of 4 which I installed when I set up my unit. I purchased a package of 2 Holmes make HEPA replacement filters (HAPF600D - B Filters) at the same time. Had I researched this better, I would have purchased the same box of 2 filters, plus 1 lone filter (same model #) since the unit requires that all three filter be changed when the red light indicates the filters be replaced. I am not aware of any distinction between an HAPF600 and an HAPF600D filter and I couldn't find this out on the Holmes website, either. Perhaps (but not sure) the "D" version removes either different allergens or more allergens from the air. As far as the "B" designation, I believe this identifies these as HEPA filters versus the "C" designation applied to the carbon filters.

It comes with one filter. If you are going to use a lot it would be wise to get a backup. I hope this helps.

I've read elsewhere that HEPA filters when they are brand new are not very effective. Over time they actually get more effective, up to presumably a saturation point and then get less effective again.I've vaccumed the HEPA filter in this unit with my HEPA vacuum to extend its life by a few months. This seems to work fine. Presumably you'd need a microscope or a really expensive piece of equipment to measure air quality for sure.The charcoal filters are cheap enough and get dirty enough I'd just replace them regularly.

Yes, one pre-filter and the HEPA filter. You will want to buy some pre-filters with your order. When your machine shows it needs changing you can either vacuum it or change it out. I have an older machine and have yet to need to change the HEPA filter.

Please read your furnace manual, but I have never heard of only using 1 kind of filter, any kind should work depending how much filtration you want.

This unit takes these filters: Holmes HEPA Type Filter HAPF30D-U2, Filter A, 2 Pack

The filter should be changed every 6 months if used continuously. HEPA filter traps very fine particles, down to 0.3 micro; and the carbon filter absorbs the small and other particles from the air. People are always surprised when they see the old one vs new one (and that's only the big particles trapped). The replacement filters are $20.

Pure HEPA filters are the best for the money. This particular model is very good I have 2 I recommend it.
