It brings in filtered outdoor air and removes stale indoor air at the same time, while recovering part of the heating or cooling energy. It runs at 20-30 dB, offers three fan speeds (28, 32 or 35 CFM), and can be controlled from the unit, a remote or WiFi.\u003c\/p\u003e\n\u003ch3 id=\"why-sealed-rooms-need-ventilation\"\u003eWhy sealed rooms need ventilation\u003c\/h3\u003e\n\u003cp\u003eModern apartments with tight windows and running air conditioners often have little natural air exchange. Carbon dioxide, odours, moisture and indoor pollutants can build up, which can make a room feel stuffy and may affect sleep and comfort. Opening a window brings in fresh air, but also outdoor dust, noise and heat. The AT501 is designed to exchange air while filtering it and reducing the energy penalty.\u003c\/p\u003e\n\u003ch3 id=\"best-for-not-for\"\u003eBest for \/ Not for\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eBest for:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBedrooms and master bedrooms\u003c\/li\u003e\n\u003cli\u003eSmall apartments and studios\u003c\/li\u003e\n\u003cli\u003eHome offices and guest rooms\u003c\/li\u003e\n\u003cli\u003eNurseries and kids' rooms\u003c\/li\u003e\n\u003cli\u003eSmall classrooms and offices\u003c\/li\u003e\n\u003cli\u003eGarages, workshops and tiny homes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 id=\"key-features\"\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnergy recovery:\u003c\/strong\u003e a heat exchanger returns part of the energy from outgoing air to incoming air, reducing the load on your air conditioner compared with an open window.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFiltration:\u003c\/strong\u003e G3 dust filter as standard; HEPA filter available as an option.
