Filter Description
The FILTI® permanent washable filter uses specialized nanofiber technology to offer a MERV 13 efficiency rating. The FILTI® filter does what other washable filters cant; providing permanent, high efficiency filtration. The FILTI® filter provides 3 layers of protection - LAYER 1 - meltblown layer designed to capture larger particulate matter and engineered for increased dust-holding capacity / LAYER 2 - patent-pending nanofiber technology captures the smallest particles and ultra-fine pollutants / LAYER 3 - downstream scrim acts as a supporting layer for the nanofiber and provides additional reinforcement
FEATURES:
FILTI® Permanent Washable MERV 13 Filter - 14" X 24" X 1"
Uses Patent-Pending NanoFiber Technology - out-performs electrostatic washable filters - and doesn't become less efficient after washing
MERV 13 efficiency rating while filtering atmospheric particulate matter that an average disposable filter doesn't
The FILTI® filter could save you up to $100 a year, upwards of $1,000 over the course of 10 years
Save our landfills! Over the course of 20 years, the average homeowner would contribute 16x more waste to landfills using a disposable filter versus a FILTI® washable filter
Use again and again - simply rinse, reuse, repeat!
