Type of Filter

Like all Hunter air cleaners, this one has a HEPA filter That can remove up to 99.97% of particles 0.3 microns and bigger from the air. It can get rid of most allergens.

There is also an activated carbon pre-filter. Activated carbon is good for removing odors. There is not much carbon in the filter, so we don't think it will do an effective job.

If you really need an air purifier to remove odors or chemicals, we would recommend a different air purifier. Look into one by Austin Air, IQAir, or AllerAir.

Maintanence Cost

This is the part that we feel hurts this air purifier. It has two filters that must be replaced. The pre-filter has to be replaced every 3 months. They cost about $28 for a two pack.

The HEPA filter should be replaced every year. It cost $60.

So the one year cost is about $116. This is cheaper than some other air purifiers. We think it is still on the expensive side. Think carefully about this before you buy this one.

Technical Details

This air purifier will clean a 20 by 20 foot room. That's 400 square feet. This is a large area. It will probably work well in any room of your house. In an area this size, this machine can provide 6 air exchanges an hour.

What is CADR?

CADR Ratings

The CADR rating is very good too.

  • Smoke 260
  • Dust 260
  • Pollen 245

It has a 3 speed fan. While the lowest speed will live up to your whisper quiet expectations, the two higher speeds are a bit noisier.

The Hunter QuietFlo 402 measures 16.3 inches X 9.3 inches X 20.3 inches (L X W X H).

It comes with a 5 year warranty on the motor. There is a 1 year warranty on the grill and cord.

Our Recommendations

This is a good air purifier to use in a large size room. The HEPA filter is important because only HEPA can remove most of the allergens from the air.

The pre-filters will work well keeping larger particles out of the HEPA filter. However, we think there is not enough carbon to do an effective job of removing odors. If odors are not a concern for you the Hunter QuietFlo 402 will do a good job.

We also don't like the maintenance cost. We think that $116 a year is a lot to pay for replacement filters. This is less than the QuietFlo 90 or 85. Consider this before you buy an air purifier.

We feel that this purifier does a good job. You will have cleaner air and less allergy symptoms. We feel that the maintenance cost are high. If you are willing to live with paying $116 a year for filters, this will be a great machine for you.
