The Morento MR5866 Smart Air Purifier isn’t the most powerful, feature-rich, or stylish air purifier on the market. However, it does perform well in small to medium-sized spaces, is inexpensive, and doesn’t require expensive filter replacements, making it a good option for budget-conscious shoppers.

How we tested

If you search for “air purifier” on Amazon, the Morento MR5866 Smart Air Purifier is likely to be one of the top picks. This simple unit has hundreds of positive reviews and is often on sale, sometimes for as little as $79.99. It sounds like a great budget alternative to some of the top air purifiers out there — but does the Morento MR5866 offer good value for money?

Its features are quite impressive for the price. The Morento MR5866 has three different filters, two air intakes, and covers an area of up to 1,290 square feet (120 square meters). What’s more, it supports a dedicated app, voice control, and air quality monitoring, and can be connected to Amazon Alexa and Google Assistant.

This air purifier is a little more advanced than the Morento HY4866, a model we rated 4 out of 5 stars about a year ago, so our expectations were high.
