IQAirV5-Cell Filter 5Pk- Genuine Replacement Air Filter HealthPro Plus - Activated Carbon & Alumina Filter for Versatile Gas and Odor Control - Swiss Made Filters for Air Purifiers - 5 Pack

The product is fantastic. I recommend buying it directly from the supplier rather than allowing the order to be fulfilled by Amazon. This particular product needs to be handled carefully. There was lots of black suit and spilled bits of carbon. The filter is usable after getting me very dirty, cleaning it up.

great product

it did improve the air quality.

Not much to say here. This is a direct replacement product. It does it's job. There are plenty of knockoffs for half the price but they contain half the carbon as this one or less and who knows the quality of the carbon they contain.

Thought these filters were going to be super expensive and difficult to install. Love the product. It cleans the air of our entire house and works extremely well. The machine is little noisy if you're running the higher settings.

This is the right filter for my IQ

I bought one to replace the filter in my IQAir unit after the replacement indicator came on following several years of service at low fan speed. The first filter worked great, and I am confident this one will too. My only complaint is that this unit consists primarily of activated carbon in a cardboard box. There's a tiny amount of alumina based potassium permanganate mixed in. The high cost simply isn't justified by the components of this filter.I have for a long time used activated charcoal pellets in my home-made ventilation filter. Several pounds of the pellets can be purchased at a pet supply store or here on Amazon for less than ten dollars. The pellets are the same ones that are in this V5 filter, and unlike the IQ Air's HEPA particulate filter, the charcoal works even when a lot of air bypasses the filter. It works by absorption, not mechanical filtration. That's why a box of activated carbon pellets (or less effective Baking Soda) works to absorb odors if you just put it in your refrigerator without any complicated sealed air handling process. I pass my home's ventilation intake air through a few pounds of carbon pellets sandwiched between two furnace filters -- that's essentially what this V5 is doing.For ventilation air, the carbon works well to remove ozone (which is what becomes of smog after it's been hanging around in the atmosphere for a while). I live downwind of California and its pollution is mostly ozone when it reaches my house several hundred miles from the urban areas. As an indoor filter, the V5 works to filter/absorb indoor pollutants and odors quite well, but it's limited by the low flow rates of the IQ Air due to the intense noise of the fan at anything but level 1.
