So when you try to stuff an actual 20x20x1 into the housing, it doesn't fit-up properly at the bottom, and distorts the plastic housing slightly which exacerbates the problem. I put in a 3M Filtrete 20x20x1 MERV 11 and it crushes the filter cardstock frame. This is irritating considering the cost of premium filters. The product information should really be specific about this detail. **Q: Will the motor overheat while using a merv-13 20x20x1? i've experienced overheating in other lasko fans in diy air filter setups using a 1inch filter.** A: The FF305 was specifically designed to ensure there would not be any motor burn out regardless of what 20x20x1 filter was placed in the unit. That is based on the motor and the filter housing. Please note though, there would be a reduction in air flow if you went from a MERV 10 to a MERV 13 filter just as you would see an increase in air flow if you went from a MERV 13 to a MERV 10. Just remember to regularly change whatever filter you choose to use. **Q: Is t just 110 volts or 110-220v so international buyers can also benefit ?** A: It is just 110 volts **Q: Does the filter go on the "back" or "front" ("intake" or "output") side of the fan?** A: The filter goes in the compartment on the back of the fan, the intake side. I love these fans. They are invaluable during allergy and wildfire season. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 軽いし強力です。 *by T***L on July 27, 2025* 部屋が排気能力ばかりで吸気が足りないと思った為購入しました。ベランダへ出る窓の前で回す事でしっかり換気できるようになりました。二酸化炭素濃度としてはこの製品なしの時は 500 PPM 程度までしか下がらなかったのが、この製品を使うと簡単に 450 PPM 程度まで下がるようになったので数値的に効果を実感できています。音は無音とは程遠く、しっかりと聴こえるのですが、不快ではない低い音が安定して聴こえているので自分は気になりません。若干残念だった点は最初から何かにぶつけて外装の一部がはげている部分があり、そこに錆が生じていたことですが、さび落とし後にさび止めを塗って対処しました。ベランダへの窓の前に配置しているので使う時に毎回少し移動させていますが、軽いので全く苦になりません。とてもお勧めできる商品です。 ## Frequently Bought Together - Lasko Air Flex 20" 2-in-1 Box Fan and Air Purifier in One with MERV10 Air Purifying Filter for Cleaner and Cooling Breeze, 3 Speeds, Steel Body, FF305 - Aerostar 20x20x1 MERV 8 - 6 Count - High Efficiency Pleated HVAC, Furnace & Air Conditioner Filters - Removes Dust, Lint, Mold & Allergy-Causing Pollen - Simply 20x20x1 Air Filter, Merv 8, MPR 600, 6 Pack, Furnace Air Filter for HVAC (Actual Size: 19.75"x19.75"x0.75") DUST, Pet, & Allergy Control --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/744521226-lasko-air-flex-20-2-in-1-box-fan-air](https://www.desertcart.tn/products/744521226-lasko-air-flex-20-2-in-1-box-fan-air) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-15*
