Review: A whole lot cheaper than hiring a tech - Worked well for me, made it easy to test air flow thru different filters. Allowed me to determine the highest MERV rating I could use without stressing the blower in my HVAC and shortening its lifespan. A little expensive for something I won't use often but a whole lot cheaper than hiring a tech

### ⭐⭐⭐⭐⭐ Best Manometer for the price!
*by E***T on August 4, 2025*

Purchased a cheaper more cost effective manometer at first, which I should have just purchased this one from the start. Seems to be very accurate, and easy to read . Definitely cannot go wrong with Fieldpiece , if you’re looking into purchasing a manometer, don’t waste your time with other cheaper brands, this is worth its weight in gold.
