less expensive and better

This is my second purchase of this item. I had in the past always shopped for the highest MERV I could find but was advised by my A/C Maintenance company that was not the best idea because the higher MERV doesn't allow the air to flow through as easily causing the A/C to have to work harder SO, I switched to this lower MERV saving myself some money without sacrificing quality..win/win

Well Made and Very Effective Filters

This is our go-to filter brand. They arrive in 3-5 days, fit the HVAC unit well and effectively keep our home's dust levels down. Much less expensive than filters at Lowe's.
