This Texas-based manufacturer has developed an excellent reputation by being at the forefront of the industry for over 15 years.<\/p>\n\n\n\n<p>Alen is also known for its above-average prices, and the BreatheSmart 75i, with a price tag of $799, is undoubtedly high-end. You might be here because you wonder whether it&#8217;s worth spending the extra money on this device, and that is why I bought an Alen 75i to test it in the same space I&#8217;ve tested over 100 air purifiers since 2020.<\/p>\n\n\n\n<p>The overall score of the Alen 75i incorporates first-hand data results from our battery of tests, as well as our ratings for customer service, brand transparency and design &amp; UX. Check out the full scorecard below to see the split of categories.<\/p>\n\n\n\n<div style=\"max-width:100%;margin:auto\"><script

I love that it visualizes sensor readings in easy to understand charts for PM2.5, tVOC, CO2, temperature and humidity &#8211; and the data is easy to export, too.<\/p>\n\n\n\n<p>One thing this app is lacking is the option to adjust the sensitivity in the auto mode to make sure it hits top speed when it needs to. This is something that other manufacturers like Levoit, Xiaomi and IQair have introduced that I really like. However, to be fair to Alen, the auto mode in the 75i reaches full speed when there is a high level of pollutants in the air by default.<\/p>\n\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n<p><\/p>\n\n\n\n<p><\/p>\n\n\n\n<div class=\"gb-headline gb-headline-eabe930c gb-headline-text\"><\/div>\n\n\n\n<p><\/p>\n\n\n\n<h2

our testing, I used a sound level meter to measure how much noise the Alen 75i generates at each of it fan speeds.<\/p>\n\n\n\n<p>Reaching 57.5 dBA at top speed, the 75i is quieter than the Levoit EverestAir, the IQAir Atem X and the Rabbit Air A3 but it is louder than the Dyson BP06, the Airmega ProX and the Blast Mini from Smart Air.<\/p>\n\n\n\n<img loading=\"lazy\" decoding=\"async\"

That said, you will lose Alen\u2019s lifetime warranty if you go the generic filter route, so you would need to decide if those $25 savings are worth losing that.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<div class=\"gb-headline gb-headline-eabe930c gb-headline-text\"><\/div>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"gb-text toc-include\" data-name=\"Is it worth it?\" class=\"gb-text toc-include\" data-name=\"Is it worth it?\" id=\"bottom-line-should-you-get-an-alen-breathesmart-75i-1h2\">Bottom line: Should you get an Alen BreatheSmart 75i?<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"a-powerful-air-purifier-that-can-be-customized-with-filters-packed-with-carbon-for-serious-odors-and-vocs-1h3\">A powerful air purifier that can be customized with filters packed with carbon for serious odors and VOCs.<\/h3>\n\n\n\n<p>I have used Alen air purifiers for many years and something I can vouch for is how they continue to support older models.
