Review on 🔍 Efficient Clean Replacement Filters for Lift Away: Enhance Filtration Performance by Tim Burns

All three filters fit perfectly: tongue washer, foam cylinder fits over Shark filter housing and rests on disc filter, HEPA filter fits behind molded door and is a tight fit, but the original was too tight. Let's assume it needs to be tight to force air through the filter rather than finding a way around gaps. Prices are much lower than manufacturers. Find errors in this purchase.
