Very Quick
"* Easy to put on main filter and very effective.""* Purchased the filters so i would not have to wait when they needed to be changed."
"* I do not recommend Honeywell brand HRF-AP1, HRF-APP1 or 38002 because : (1) Prefilters HRF-AP1, HRF-APP1 or 38002 (all made in Mexico) are thinner and much lower quality than the original prefilter that comes with the air purifier or the generic ones made in US, Korea or China that I bought before."
"This particular filter fits numerous sizes so you have to cut it down yourself to fit your model."
"* If I am to give tips and guidelines you should not tell me how many words are required."
"Have never had this problem with ones bought at a big box store."

Quick
"* Purchased the filters so i would not have to wait when they needed to be changed. They made it to my front door on the day promised. Thank you!!!!""* I do not recommend Honeywell brand HRF-AP1, HRF-APP1 or 38002 because : (1) Prefilters HRF-AP1, HRF-APP1 or 38002 (all made in Mexico) are thinner and much lower quality than the original prefilter that comes with the air purifier or the generic ones made in US, Korea or China that I bought before... Without prefilter, the HEPA filter (about $60 or more) lasts only 4 to 6 months, instead of 1 to 2 years... The generic filters I have bought are less expensive, thicker and have much less loose black carbon dusts than ones from Kaz and Honeywell."
"This particular filter fits numerous sizes so you have to cut it down yourself to fit your model. It is one large piece pre-folded in half in order to have a double or thicker layer. It seems cheaper than what I've ordered in the past which was a very, very thick filter precut."
"* If I am to give tips and guidelines you should not tell me how many words are required... Very satisfied with product and it was just what we wanted. Have not used yet so it is hard to rate."
"* After running this newpre-filter, I noticed a strong chemical smell akin to wood treatments or wood glue... Have never had this problem with ones bought at a big box store. Perhaps I was unlucky, but the quality control may be missing some bad filters."
