X6672 Lennox Healthy Climate 16x25x5 Merv 16 Filter

Second time purchasing this item

Excellent product at a good price.

This filter is for the active(as in not a regular passive air filtration for central air/heating) aircleaner from Lennox(or other brands) it isnt an ordinary filter and is not to be used that way. You use it with a separate aircleaner that plugs into your climate system of air/heating and with mine also a humidifier/dehumidifier unit. The MERV 10 is quite enough to get rid of my allergy to pollen or some grass or what but the point is, when I turn it off/open a window my cough returns, I feel less energy when I turn it on and close the house the problems I have with my environment(Oklahoma humidity) goes away within minutes! This is an upgrade and at a high cost but is slightly more efficeint at this job though as with the cheaper one(MUCH cheaper!!!) it only lasts about a year. Dehumidifers can correct some problems and make it last the full year if not, it may begin to fail in less time than that if you live in high humidity. for example: Georgia, Central(OKC) and NW Central(Tulsa or Stillwater) parts of Oklahoma, or the Everglade, my bro lived in Florida, has it much worse than me. the thing lasted a month!(I am told)

as advertised, very close to HEPA

We have a recent model Lennox furnace (2 years old) and it has no problems with the extra resistance presented by this filter. We installed it immediately after getting the ducts cleaned, and I can say that there is significantly less dust visible around the house.

It is exactly what I needed to keep my furnace running great.

We used this filter for one year...it did well. Just had our annual check up passed with flying colors thank you for a great product

Easy installation. Arrived within a few days.

Pretty price for a filter

Even though I have a service contract, my dealer wants $160 for these. For less than half that, I can just change it out myself, or order in advance and hell install them. I have a Lennox system, and this one fits like it was made for it (which it was.) I dont know if the 16 is all that much better than the 11, but I dont seem to have much dust in that building.
