Review on Upgrade Your HVAC System With Filterbuy MERV 8 Air Filter - Perfect Replacement For Aprilaire Space-Gard 104 / Model 2140 (15.75X27.63X3.75 Inches) by Kevin Barbon

Not the best, but not the worst upgrade for your HVAC system. The Filterbuy MERV 8 Air Filter does its job in keeping your air clean and fresh, but it doesn't surpass other filters on the market. Although, the easy replacement for the Aprilaire Space-Gard 104 / Model 2140 makes it a less daunting task to maintain a healthy living space. Overall, it's a decent purchase for those who appreciate a little clean air and a little more money in their wallets.
