AlpinePure 211 & 411 (MERV 11 Filters)
AlpinePure 211 and 411 MERV 11 fi lters are avail able in both 2-inch
and 4-inch sizes. "MERV" stands for Minimum Effi ciency Reporting
Value, an industry standard which sets a rated value on the ability
of a fi lter to trap particles ranging in size from 0.3 to 10.0 microns
from the air we breathe. Most ordinary, inexpensive fi lters found at
hardware stores are MERV 4 or lower—they are simply ineffective
in capturing smaller particles. MERV 11 fi lters are much more
effi cient for both small and large particles including pollens, mold
spores, dust, fungal spores, and pet dander. In addition, these fi lters
are pleated to increase the surface area, allowing for more holding
capacity and less frequent replacement.
Replacement
If you use pleated disposable fi lters, change them regularly, before
they accumulate too much dirt. Do not attempt to clean a disposable
fi lter. Simply throw it away and reinstall a new one. Do not turn a dirty
fi lter over to the clean side and reinstall it-- this results in blowing the
accumulated dirt right back into the home. AlpinePure 211 and 411
fi lters can be purchased through your local WaterFurnace dealer.
The suggested replacement interval is 4 to 6 months, depending
upon conditions and lifestyle.
