Buying Guide

Clean air matters for health. Good filters keep dust away. Your home feels better with clean air.

I changed my filter last month. The air felt fresh in days. My family breathes easier now.

  • MERV Rating: Higher ratings catch more particles. MERV 8 works for most homes. MERV 11 or 13 is best for allergies.

  • Filter Life: Most filters last 3 months. Some can work up to 12 months. Change them on time for best results.

  • Filter Type: Pleated filters catch more dust. Electrostatic filters use static to trap particles. Fiberglass filters cost less but work poorly.

  • Actual Size: Check the exact size before buying. 20x20x1 filters are often smaller. Measure your old filter to be sure.

  • Pack Size: Buying in packs saves money. Six-packs last a full year. Two-packs work for trying new brands.

  • Air Flow: Good filters let air pass easily. High MERV may restrict air flow. Balance filtration with system needs.

  • Brand Quality: Some brands work better than others. Made in USA filters often last longer. Read reviews from other buyers.

  • Special Features: Some filters have app reminders. Others use recycled materials. Pick features that matter to you.
