A fantastic gift for people who smoke

Alen Breathesmart Flex vs 45I The unit contains only one filter. To capture large particulates, there is a hepa filter and an outer filter. To extend the life of the filter as a whole, I vacuum the out filter every 1-2 weeks.I purchased my unit in the fall and have yet to change the filter. I'm guessing it'll be once or twice a year. When you acquire a new filter, you can choose from a variety of styles based on your needs. I mostly filter the air for dust. However, fet filters can be used to remove odors and other contaminants.  Because air intake happens on the side and air outflow is positioned at the top, positioning with the rear along a wall is perfectly acceptable. We hope this was helpful! Sincerely, Customer Service Team at Alen 

If you're trying to set up WiFi via Gosund, hold the auto button to put your purifier into pairing mode. One press turns it on and the WiFi icon flashes; another press turns it off; you'll see it flash and ultimately turn off if you've switched off the WiFi.  onizers have been shown to produce more CO2 than they "benefit," therefore avoid them. This machine has no ionizers, which is why it is so effective.  The item does have WiFi capabilities. These units can be controlled via TUYA's "Smart Life" APP, which is available in app stores. Download the APP and follow the instructions to sync the unit. By pushing the Auto button for 5 seconds, the unit can be put into pairing mode (the WiFi light will blink). Simultaneously, the unit function with the Smart Life APP has not been fully fleshed out or tested, and it may be buggy. Alen is not currently configured to support the APP.
