Hunter air cleaners are made by the Hunter company. It was founded back in 1886 to sell ceiling fans. These first fans were water powered. They were truly innovative and unique for the time period.
Today Hunter still has the same innovative spirit. They manufacture ceiling fans, thermostats, humidifiers, and air purifiers.
They have been making air purifiers since the mid 1990s.
The line of Hunter air purifiers include the QuietFlo, HEPATech, and Permatech product lines.
Hunter Quietflo 401
Hunter currently produces 5 QuietFlo models. There are several older models still available. The replacement Hunter air filters and pre-filters are still available.
Independent test of some Hunter air cleaners showed that 98% of the particles were actually removed. This is not 99.97%, but it is still very good performance.
These Hunter HEPA air purifiers use true HEPA filters. These filters can trap and remove 99.97% of particles 0.3 microns in diameter or larger that pass through the filter.
Quietflo air purifiers use two Hunter filters. In addition to the HEPA filter, they also have an activated carbon pre-filter.
The activated carbon pre-filter is supposed to remove odors from the air. The pre-filters do not have a lot of activated carbon. This means that they are not really going to be very good at removing odors.
All Quietflo Hunter air cleaners all have whisper quiet operation. They are quiet on the lowest fan speed. They do tend to be a bit noisy at the higher settings.
