Who is Merv and why does he care about my air filters?

Good question.

Merv is not the name of a talk show host (if that goes over your head, you'll just have to Googlize it). Hint: think Griffin.

Actually, MERV stands for Minimum Efficiency Reporting Value, which is a rating system established by the American Society of Heating, Refrigerating and Air-Conditioning Engineers.

Say that five times fast.

I know – “that, that, that, that, that.” Sorry I said anything.

MERV is designed to let you, the consumer, know the purpose for which the filter is intended.

This is a chart I “borrowed” from Wikipedia. Hey, I donate money to support them.

At Filters4Air we give you a choice – MERV-10, or what we call High Performance Allergy, and MERV-13, or what we call High Performance Allergy Plus.

If you start sneezing due to pollen, grasses, smoke or whatever – you need a new high-quality filter.

Hey – we sell high-quality filters. Who knew?

Anyway, we deliver right to your door. We also install, if you need help. Win-win.

Just go to our website and get your order in because winter is coming and that means your heater is on all the time, and that places as much strain or your air filters as air conditioning.

I mean, they are called “air filters” not “air conditioning filters.”

Just saying.

Aaargh, I hate that expression.

Hope you check us out at filters4air.com and thanks for the ear !!!
