Once you are done with removing the filter, you need to deep clean your filter using a vacuum cleaner. Use a soft-bristled brush or a vacuum hose with a brush attachment to gently clean the surface of the filter. This will help remove any loose debris, hair, or other trapped particles that have accumulated on the filter.
That said, there are a few other models, like the ultra-sleek Molekule and the Blueair Blue Pure 411+ that don’t technically have HEPA filters but use other technologies for a similarly squeaky-clean result. These devices come in a range of sizes, and the best one for your space depends on where you intend to place it. In
general, the more square footage you want to purify, the bigger the unit tends to be. The Levoit 400S air purifier makes an impressive claim – to completely purify your indoor air in just a matter of minutes. It uses a True HEPA 3-stage filter to capture airborne particles, such as smoke, dust, pollen, and pet dander.
The Alen BreatheSmart features a HEPA Pure filter that is certified to capture 99.97% of airborne particles down to 0.3 microns. This works in combination with the device’s Laser Smart Sensor, which also detects airborne particles down to 0.3 microns, to effectively clean your air of dust, pollen, allergens and dander. Additional models can capture odor and smoke as well, and carry a higher price because of those features. This air purifier cleans up to about 1,300 square feet twice an hour without making a lot of noise. In fact, Alen claims the technology in the BreatheSmart is twice as quiet as that of its key competitors, even on Turbo speed.
In addition, you can leave a comment in the comment box below with any question or problem you may have encountered when using a Levoit air purifier. I also recommend reading all the detailed reviews posted on the Air Purifier First website or our YouTube channel. I would advise everyone not to rely entirely on the filter reset indicator and check the filters from time to time if they are dirtier than they should be and should be replaced before the recommended time.
It’s safe to sleep with an air purifier on, and especially if you have allergies or asthma, it can be quite beneficial. The air purifier makes for a more comfortable sleeping environment and can improve your sleep. Just be sure to set your device in a clear, clutter-free space if it’s going to be running while you’re sleeping.
Replacement filters cost $19, and if you stick to the six-month replacement schedule, they add up to just $171 (nine filters) over the course of five years. The total five-year running costs are thus just $200, about 60% less than the costs of the Levoit Core 300. Add in the Blue Pure 411 models’ quiet operation and good looks, and they are an attractive option for small spaces.
Senior staff writer Tim Heffernan has been at Wirecutter since 2015 and has overseen this guide since then. Since 2017, he has conducted extensive real-world testing of air purifiers in his New York apartment and in Wirecutter’s New York and Los Angeles offices. Tim has also lived with most of our picks, running them 24/7 for months—sometimes years—on end in his apartment.
You can also download the Alen Air app, which provides an overview of your air quality and other related statistics. In addition to filtering out 99.97 percent of airborne particles down to 0.3 microns, this GermGuardian purifier
contains a UV-C light that helps sanitize the air by reducing airborne bacteria, viruses, and mold. The UV-C light is part of a three-stage filtration system, including an activated charcoal pre-filter and a HEPA filter.
