Buying Guide: Basement Air on a Budget
Keep these points in mind before you buy.
Count the filter cost
Check the price and life of the replacement filter before you buy. A cheap purifier with expensive filters can cost more over two years.
Carbon for musty smells
EPA notes carbon filters remove gases best when there is a large amount of material, the thicker the better, so favor deep carbon beds for basement odors.
Keep basement humidity in check
EPA advises keeping indoor humidity below 60 percent, ideally 30 to 50 percent. A dehumidifier and an inexpensive humidity meter make that easy to track.
Budget Basement Tips
Save money and stay fresh:
- Size the purifier to the room you use.
- Run Auto Mode, not high, all day.
- Vacuum the pre-filter monthly.
- Control humidity before buying more.
