Activated carbon pre-filter fits all round HoneywellHEPA air cleaners

Helps reduce household odors, trap large particles and extend HEPA filter life.

Simply cut the pre-filter material to the size of your air cleaner's HEPA filter (instructions included).

Pre-filter lasts as long as 3 months, depending on use. For smaller air cleaners, this pre-filter material may be large enough for 2 replacements (as much as 6 months of use).

Rating: - Pre-Filter Fits All Honeywell HEPA Air Cleaners
I follow the manufacturer's recommendation to change the pre-filter every 3 months on all my Honeywell Air Cleaners with HEPA filters. These replacement filters come boxed in a set of two. The pre-filter simply wraps around the round HEPA filter, which is inside the unit, and attaches to itself by means of two velcro fasteners. It takes less than five minutes to change the pre-filter. In between changes, I vacuum my pre-filters to remove accumulated dust and pet hair from them. These pre-filters do help to remove some odors from rooms, especially if you are able to keep the space enclosed where you have the air cleaner running.

Be sure to keep a box or two of these pre-filters on hand in case they become back ordered. The HEPA filter needs to be changed in 1-3 years, depending on conditions where it is located.

Rating: - Universal Pre-Filter
This filter is larger (taller) than it needs to be for most machines. You simply trim the filter (and it's got pre-made perforations) to the height of your machine. And yes, this means that if you have one of the smaller machines, one which is less than half the height of the pre-filter, you might get two pre-filters for the price of one. Bonus.

Rating: - Filters out dirt, dust, feathers, bug, hair, etc. Oh, my!
This is a filter. Air passes through it due to differential pressure. The mesh like structure impedes the movment of dirt, dust, feathers, bug, hair, etc. This fact may be evidenced by examining one after a sufficient period of use in an environment where such junk is in the air.

Forensic analysis of the mesh trapped junk may reveal fascinating detailed knowledge about the locale in which the filter unit had operated..

These mesh carbon fiber structures should be exchanged periodically for a new unit. The filth ridden one disposed of in a plastic bag, placed in the trash, and hands washed afterwards.
