What MERV rating does this filter have?

It is rated MERV 11. That captures most pollen, dust, mold spores and pet dander while staying suitable for typical residential systems.

Wash the pleated media, rinse it, and let it dry completely before reinstalling. Reinstall only when fully dry to avoid moisture in the ductwork.

Will it fit my furnace?

It comes in standard nominal HVAC sizes. Measure the old filter's width, height and depth and match those figures, since nominal and actual dimensions can differ slightly.

Is it worth it over disposable filters?

Over several years the reuse offsets the higher upfront outlay, and it cuts filter waste. If you would rather not wash and dry a filter, a disposable MERV 11 is simpler.

How does it compare with washable electrostatic filters?

This one carries a defined MERV 11 rating and pleated synthetic media. Many washable electrostatic filters have no independent MERV rating, so filtration is less predictable.

One washable pleated filter. Installation guidance is limited, so check K&N's site or your HVAC manual for the correct airflow direction before installing.
