Alen is a US-based company that manufactures top-rated HEPA air purifiers. They're one of a select few companies in the industry that stands behind their products with a lifetime warranty. Their air purifiers are compatible with the Alen Air App, which allows users to monitor and control their air purifiers remotely and get insights about air quality. Alen has been in business for nearly 20 years and has been accredited by the Better Business Bureau since 2012.

Three highly-rated air purifiers

Alen sells three air purifiers - blessedly straightforward in an industry where some brands offer 20 options or more. (How are you ever supposed to narrow that down?) Each has a 4.8-star rating average based on thousands of sortable, filterable customer reviews, which you can read right on their product pages. Don't worry about your electricity bill with any of these - they're all Energy Star certified, so you're getting clean air without wasting power.

Match your air purifier to your decor

Something we appreciated about Alen's air purifiers is that you can separately purchase magnetic color panels to match your home decor. You can choose from white, oak, weathered gray, brushed stainless, graphite, and espresso panels. That means your air purifier can be cohesive with any room's design. If you redecorate or move the purifier, you can easily switch to a new panel color to fit the new space. They cost $59 each.

Purifier for large rooms is $637

For large rooms up to 2,600 square feet, the 75i is the champ. Like all of the air purifiers sold by Alen, it uses True HEPA filters. You can adjust the 75i's speed automatically based on how clean or dirty your air is. You get five fan speed options, and it's super quiet, ranging from a whisper-like 23 dB to a still-comfortable 50 dB. The 75i is a powerhouse with a CADR of 347, meaning it cleans air thoroughly. It's priced at $636.65, and its filter lasts up to 15 months, although it costs $99 to replace, which is expensive.

Bestseller is $429

For medium-sized rooms up to 1,600 square feet, check out the 45i. This one is Alen's bestseller. You get four fan speeds, and it's just as quiet as the 75i. The 45i has a CADR of 245, and can purify your mid-sized space's air within 60 minutes. It's more budget-friendly at $429, and its filter needs changing after about a year, costing $69.

$249 purifier doesn't have speed adjustment

For smaller rooms up to 1,400 square feet, Alen offers its FLEX model. It uses True HEPA filters like its bigger siblings but doesn't have the automatic speed adjustment. You still get four fan speeds and the same quiet operation. The FLEX has a CADR of 225, which is great for its size. It's the most affordable at $249, and its filter lasts about a year, also costing $69 to replace.

Save 10% on filters

All these models can clean 99.9% of tiny particles in the air that are bigger than 0.1 microns. Just remember, regular filter changes are necessary for your air purifier to work its best, so you need to stay on top of this maintenance task. If you're worried about forgetting, you might benefit from the Alen Autoship program. Alen will deliver your filter replacements according to the schedule you give them, and you can skip or cancel a delivery anytime. You'll save 10% on filters and shipping is free.

Choose the filter that matches your air quality concerns

Did you know you can switch up the HEPA filters in your Alen air purifier to tackle different air quality issues? The Pure filter is designed to catch allergens, dust, and mold. If you're dealing with chemicals, cooking smells, or other household odors, you might want to try the Fresh Air filter. It uses medical-grade HEPA with carbon to handle those issues. And if you have strong smells in your home created by pets or kids, the Odor Air filter could be your best bet. It uses medical-grade HEPA with an odor neutralizer, and it still catches all the usual stuff like pet dander and allergens.

60-day guarantee

Alen offers a 60-day money-back guarantee. They're so confident you'll notice a difference in your air quality within 48 hours that you'll get a full refund if you're not satisfied. The only cost is the return shipping. However, they won't accept opened filters with the original plastic wrapping removed.

Lifetime warranty depends on filter proof

Your Alen Air Purifier comes with a lifetime warranty, as long as you register your purifier and keep an active air filter subscription with Alen. If you don't have a subscription, you'll need to show proof of genuine Alen filter purchases at least once a year (or every 15 months for the 75i model) to maintain the warranty. The factory warranty covers any defects in materials or workmanship for the first year after your purchase. After that, Alen will replace or repair your purifier for free for the lifetime of the product, as long as you meet the subscription requirements.

Customers are happy

Customers really like Alen air purifiers. They say it's easy to set them up and replace their filters. People with asthma and allergies feel better immediately, and those in areas with wildfires can breathe easier, too. People enjoy extra features like white noise and dimmable lights for use in bedrooms. Reviews also say that Alen's customer service is helpful whenever issues arise. We're pleased to report that Alen has an "A+” from the Better Business Bureau - the only air purifier company in this review to meet that standard. For all these reasons, they're our top pick.
