Conclusion

The most effective furnace filters for allergies are those that capture the smallest particles, such as HEPA filters. While these filters are more expensive, they are worth the investment if you or a family member suffers from allergies.

Other effective options include electrostatic filters and activated carbon filters. Be sure to change your furnace filter regularly, as a dirty filter will not be as effective at capturing allergens.
