It says it has a permanent filter, yet there are offers to purchase replacement carbon filters with it. Are those extras that you can add for odor?

Yes, the permanent filter is for dust and allergens. The carbon pads are just to absorb odors and are not needed just for dust and allergens.

There is a hepa filter that is permanent but there are carbon filters that need to be replaced every 3 months for odor.

There are two processes going on, a permanent filter in the front and two replaceable ones right behind that. Careful, they are sold in boxes of three so order two boxes to keep it even.

It comes with the filter. I replaced it after about 8 - 9 months. Works great - no odor at all. DM

Yes it does. It uses two types of filter, one which is meant to be permanent, and one which is meant to be replaced periodically. It comes ready to go with both. In the past I simply vacuumed the replaceable filter between replacing it and that seemed to work pretty well also.

It comes with a HEPA filter and a charcoal pre-filter. I would suggest buying a pack of replacement charcoal pre-filters at the time of purchase because they get used up every three months or so. I think that they reccommend it for use in rooms that are 168 square feet (12 by 14 feet). I use it in a larger room, and I think that it does accomplish something (I see less floaties, smell less kitchen odors), but its not as effective as the unit I run in my bedroom, which is a smaller area. If you have serious allergies and this is the solution I would buy a unit that is suggested to run in the size room that you have. If you're a mild allergy sufferer, then it may do well enough for you in a larger room. It comes with a HEPA filter and a charcoal pre-filter.

If there is room in your filter, you may as well just add it. However, it can take the place of your charcoal if you don't have the room. My filters not have the room, so I put it where the charcoal would. It is a nice product.

it has a carbon filter witch is way better than just the plain white filters. but carbon filters absorb just so much and than stop working. use the plastic bag when not in use to last longer. what it is capable of absorbing is hard to say. i use for keeping blown up dust when mowing grass. and helps keep smell out when target shooting indoors.i bought extra carbon filters to change each time i reach about 40hrs of use.

Yes, it does. However like other reviews I agree that the carbon bag is far too big for the filter so be ready for that.

I didn't use a permanent filter, only one time filters. Not worth spending for permanent filter it won't last long. Sorry to disappoint but after 4 of them I gave up.

This unit comes with a permanent filter that can be washed and reused. There is also a light on the unit that tells when the filter needs to be cleaned.

It has a small filter that comes with it. I replace it every so often. I use it just because it has it. I guess you wouldn't have to.

The carbon filters come with this unit. It says in the instructions that you can use it with or without the carbon filters. And my unit also has an air duct outside. I use the carbon filters to help eliminate the cooking odors.

We're using it exclusively as a diaper pail, and I wouldn't say that there's never any smell, but we don't notice anything most of the time. It's been smelling occasionally in the last couple weeks, but we've been using it for 8 months now, so I'm going to see if replacing the carbon filter will stop the smell.

This filter controlled odors for about 3 months. Once the carbon was depleted, (no longer controlled odor) it had to to be replaced. No need to clean, it either works or it doesn't.

It can definitely be used with a carbon filter. I have one in my room now scrubbing the air, it works great and is quiet. I highly recommend. This is the filter I paired it with, http://www.amazon.com/gp/aw/d/B005HT0GZ8

It comes with one filter (for charcoal) and one foam filter for the motor. I purchased the Forever filter from this site and it is wonderful...no need to buy any more filters for charcoal...and free shipping from Amazon. The filter costs about $ 30 which is what it would cost you for 4 regular filters...and I bought extra foam filters too...Love the Forever filter...pays itself in a months worth of filters. Charcoal is cheap. The foam filters need replacing about every 2-3 months

It's permanent, but the manual does say you can get a replacement filter if damaged. Only there seems to not be one anywhere, including at the Holmes website. I e-mailed them and asked them about the matter, and will come back and tell you what they say.Okay, the e-mail I got back from Holmes said they have no replacement filter for this air purifier. I don't know if anyone else has one or not.

Yes the product does come with one filter. Submerge & rinse it in cool water before use so the small charcoal sediment gets washed away. The charcoal would not hurt your pet: just might look funky with black stuff floating in the water. I have been rinsing and reusing mine weekly for 2 weeks and tomorrow will replace it altogether with a fresh one. It has held up very well and is easy to clean. At the time that I purchased the fountain, I also purchased a 3-pack of replacement filters (free shipping over $25). I have read that one can also open up the plastic filter container and replace the used charcoal with fresh charcoal, so the filter lasts even longer. I will probably not be doing this but the loose charcoal is easy to find at pet stores that carry aquarium filter supplies. Just ask for a bottle of 'aquarium charcoal' (~$5), open the used filter, remove and throw away the old charcoal, clean the white floss bag well, and replace charcoal with a similar amount of fresh charcoal. Submerge & rinse as with initial filter use. So, yes the fountain does come with one filter in the box ;). Too much info, right! :) Good luck with your purchase!
