do these filters remove allergens in the air or just odor?

Well, I have to remove dust from the filter regularly,so I assume there would be allergens attached also. Remoing allergens is not their usual purpose.

Yes, just drop in the tank. I started using them this winter in my humidifier and a have found them to significantly decrease the amount of slimy buildup in the water reservoir where the filter sits in the water and also no bad water smell from the water tank.

They filter particles as low as 4-5 microns. When I was in S. Korea I observed people wearing dust mask and these 3-M mask and filters are 1000 times better. Also the mask fits closer to the face with not gaps/openings.Loyd

That will depend on the concentration of polutants in the air of the area where you are using them. For me, they last until I start feeling too much smell (in the air that I'm breathing) inside the mask or when I start caughing too much. It means the filters are already getting too dirty. Another thing you can do is check the colour of the filter in the inner side, the small hole where it attaches to the mask. If it starts getting dark, I think you might need to change them.

I've only used them in heating mode so far and have had no odors at all- in fact the family seems to be breathing better. Maybe try in heating mode for a few minutes and/or run system for a little while with no filters just to be sure it is the filter?

I'm sure the hepa filter would pull out airborne mold but not sure about mildew. If you mean a mildew smell, I don't think so. Perhaps a dehumidifier would be a better choice.

these filters have worked well, I have used 3 of them over the last few years and will order them again.

This is a filter for the Venta Ultrasonic Humidifier. That's what I am using it in. Believe they are using the term "airwasher" in how the filter helps remove particles, dust, and others from the air.

They're made to filter retun air on a Central System that contains an Air Handler and outdoor Condensing unit. It keeps the coils clean on the Air Handler so they can remove heat from the return air efficiently and take pollen/lint out of the air. If you use them on a regular air vent (cool air blowing into house), they will only help remove dust etc from the air you breathe, but will also run up your elec bill due to the resistance of the outlet. Hope this helps...

They are thin, like the precut ones. I have a Fellows air purifier and the carbon pre-filter has to be thin, but they work well. They come in a folded sheet of carbon material and you cut them to fit your particular unit. They work as well as the precut filters, at a fraction of the cost.

My original filters were black, as well as all I've ordered since then. I don't know how scientifically effective they are, but they seem to clean the air well & relieve our allergies.

Not sure but, I think the "A Filter" refers to the fact that it is only ONE filter but my husband cuts them in half and so you can actually get two usable filters from one box. This is the first time we ordered the "A PLUS FILTER" which refers to the fact that it is supposed to be more odor reducing and stronger somehow. My husband says he does not notice a difference but I think I do. So we will keep buying this version.

As long as you change the carbon filters at regular intervals yes. The dust filter itself does nothing for odors. It's all in the carbon. Hamilton Beach sells expensive carbon pads, but if you do an Amazon search for carbon air filters, cut to fit, you can find them much cheaper. For like $6 I got months worth of the filters, all I had to do was cut them to size as they come in one large sheet. Very worth it there as it saves a lot of money.

Hi, I have the HB True Air 04383 Air Purifier and I bought these replacement filters. They do fit. As Kimberly says, you remove the cover on the Purifier and remove the 2 brackets that holds the current filters in place, and replace. The Air Purifier takes 2 filters, even though the replacement filters come in a 3 pack. And to me, these filters are unscented. There is no smell. I have uploaded 2 pics to show you how they fit. Hope this help.

Mine came set up for recirculating. The filter will not remove all odor but will help eliminate most of it. Charcol filte can be replaced when needed

You can sometimes tell if the filter has reached the end of it's useful life if you see excessive particles floating in the air. Another sign that has been mentioned by Austin Air is that you may notice a sweet smell. To help prolong the life, try removing and vacuuming the prefilter to improve airflow.

I have used these filters for the past 1 1/2 years without any problems. Sorry you encountered a problem.
