Today, when shopping for home tech, it’s best and smartest to look for a product that’s multi-functional. From a cooling fan that also doubles as a heater in the colder months to a Bluetooth speaker that also functions as a soundbar for your TV, these products give you the most bang for your buck.

In the summer months especially, tower fan and air conditioner purchases hit an all-time high — and for good reason. With several heatwaves hitting parts of the country, these pieces of home tech are more necessary than ever. But with so many folks suffering from asthma and year-round allergies, the summer is one of the most anxious times of year for some.

Luckily, there are actually a few top-rated tower fans and air conditioners that serve double duty as air purifiers, blocking out harmful allergens, dust, pollen, pet hair and more. In fact, several are certified asthma- and allergy-friendly by the Asthma and Allergy Foundation of America. Check out our top five picks below from brands like Dyson, LG, July and more.

This Amazon’s Choice bladeless tower fan and air purifier hybrid is compact, portable and extremely powerful.

ULTTY’s Oscillating Bladeless Tower Fan Air Purifier oscillates a full 90 degrees and, despite its small size, cools an entire room quickly and effectively. Its bladeless technology also makes it a breeze to clean and safe for children and pets.

However, its air purifier function isn’t an afterthought. In fact, it’s just as advanced and well-engineered as the fan component. The certified air purifier fan works on an H13 HEPA standard filter (recommended by the United States Environmental Protection Agency) and has nine speeds.

It also has three cooling fan modes and nine speed settings, allowing you to control every aspect and function. Right now, get it for 25% off on Amazon!

Dyson is another brand that perfectly executes the cooling fan and air-purifying co-functions. The Dyson Purifier Cool Formaldehyde TP09 Purifying Fan, one of the best-selling brand’s newest models, was re-engineered to deliver 50% cleaner air and features Dyson’s most advanced filtration system to date.

It has a precise, solid-state formaldehyde sensor with a unique catalytic filter that continuously destroys formaldehyde without making a single sound. From personal experience, I can confidently say that it’s the most silent fan I’ve ever used. It’s literally whisper-quiet.

This Dyson purifying fan also has an activated carbon filter that removes gases and odors and a HEPA filter that captures 99.97% of particles 0.3 microns in size. Best of all, it’s certified asthma- and allergy-friendly by the Asthma and Allergy Foundation of America.

July offers one of the most advanced, best-looking and powerful window ACs you’ll find anywhere. If you’re looking for an air-conditioning unit that looks like home decor — this thing is honestly so beautiful to look at — and also cleans the air while it cools, July is a no-brainer.

In addition to its gorgeous and extremely customizable design, the model comes with an option to add an air-purifying filter that’s super easy to install and change. There are two options to choose from: July’s Air Purifying Sky Filter and its Carbon-Activated Purifying Filters.

Both turn your AC into an air purifier, but the difference lies in what they remove from the air. The Sky Filter, which I use religiously, cleanses the air of pollen, pet dander, dust mites, mold/spores and other pollutants. The Carbon-Activated Filter is its newest release and removes smoke, car exhaust and odors from the air. Each option comes with a three-month supply.

To install them both, simply remove the magnetically attached front cover, replace the standard AC filter with one of the two mentioned above and reattach the cover. It’s that simple!

The LG PuriCare AeroTower Air Purifying Fan with True HEPA and UVnano LED is one of the trusted tech brand’s newest releases, and it’s selling out fast.

In addition to being a powerful tower fan with a beautiful, unique design, this device has an intense filtration system that produces clean air constantly. The True HEPA filter captures 99.97% of fine dust and allergens to deliver purer, cleaner air.

Taking things a step further, this fan also has LG’s exclusive UVnano LED Technology that kills 99.9% of bacteria on fan blades for an added layer of protection.

LG’s PuriCare AeroTower Air Purifying Fan with True HEPA and UVnano LED also provides multiple airflow options and coverage for small and large rooms of up to 818 square feet. This thing reaches pretty far — much farther than most tower fans.

For those looking for a portable air conditioner that doesn’t sacrifice sunlight like window ACs or take up any window space, this No. 1 best-selling Whynter is the best of the best.

With over 10,000 raving Amazon reviews and a sale price of $290 — it’s 52% off right now — this portable AC is unlike any you’ve used.

It has a dual hose build that cools a room of up to 500 square feet extremely quickly. Also, despite this feature, it’s super quiet while emitting lots of cool air. In fact, it produces less than 56 decibels of sound, which is quieter than most fans.

Its air-purifying quality, though, makes this one a home run. The Whynter ARC-14S 14,000 BTU Dual Hose Portable Air Conditioner has a washable pre-filter and an activated carbon filter that eliminate and remove chemical fumes, toxic gases, smoke, pet and other odors. The washable pre-filter also further removes large particles like dust, pet hair and dander. So, this device gets it all!
