Overbuying features — Most people use 20% of high-end prefilterhvac features. Don't pay for what you'll never touch.
Not measuring — "It looked bigger online" is the #1 return reason for prefilterhvac. Measure twice.
Waiting for the perfect deal — If you need prefilterhvac now, buy now. A 10% discount in 3 months costs you 3 months of use.
Ignoring the fine print — Some prefilterhvac listings look great until you realize key parts are sold separately.
