Review on 🌬️ Allergen Reduction Guaranteed with Filtrete Throughout by David Gagnon

As a warning to all consumers, I am doing a detailed review on this subject. I put this in my system for 30 days and this is the cause. My HVAC company said the filter was not letting air through and was causing ice to form. When I contacted them to get a refund for at least the faulty product they said the 30 day return period had expired which is correct but has it ruined my system? He also says that there is a 90-day filter and it is clearly false advertising.
