In winter, your indoor air quality can go down significantly. When you seal your house up tight so cold air can’t get in, it means that the same air will circulate through your furnace again and again. The contaminants that don’t get filtered out will just stick around, building up all season. That’s why it’s so important to find the right air filters for winter. Here are three of your best options:
- Nordic Pure. The Nordic Pure has a 12 MERV rating, putting it in the top tier of residential filters. It can remove basic contaminants, like dust, pollen, and pet dander, as well as some smaller particles, like bacteria and cigarette smoke.
- Honeywell FPR 9. This Honeywell filter isn’t officially MERV certified, but it operates at about an 11 or 12 rating, which gives it about the same effectiveness as the Nordic Pure. It’s also easier to find than the Nordic (if a bit more expensive), as it’s sold in most hardware stores.
- Filtrete MPR 1500. Rather than a MERV rating, this filter has a Microparticle Performance Rating (MPR), referring to its ability to remove particles under one micron in size. The rating is 1,500, which, again, puts it at about an 11 or 12 on the MERV scale.
If you really want the best air filters for winter, consider investing in a dedicated air purification system. HEPA filters can remove contaminants from your air with much greater efficiency — and down to a much smaller size. However, they won’t fit in your regular HVAC system without damaging it. A separate air purification system, designed for high-efficiency filters, can remove more than 99.9% of contaminants, including viruses, cooking smoke, and much more.
Whatever filter you buy this winter, don’t forget to replace it regularly. In winter in particular, filters clog up faster, due to the extra contaminants hanging around. Check the filter regularly and replace it when it turns gray and opaque rather than white and translucent.
