No matter if you’re suffering from allergies, the effects of wildfire smoke, or smog, the secret to maintaining healthy air in your home is investing in a quality air purifier. Some of the best machines can cost a fortune, but thankfully Walmart has a highly rated model on sale for a fraction of the cost.

The Dr. J Professional HEPA Air Purifier is a stellar machine that accommodates rooms up to 3,500 square feet, and filters out even the smallest particles including pet dander, pollen, smoke, dust, and odors. The best part is that you can add it to your cart for only $135 right now, which is 81% off the original price and a whopping $565 in savings.

This model is also eligible for free shipping and can arrive in as little as two days, depending on your location. That means you could be breathing cleaner air in a matter of days if you order right now.

Although it can purify rooms up to 3,500 square feet in a single day, it can clean the air in a 700 square-foot room up to five times within an hour, which is the size of most living rooms and bedrooms. It uses a true H13 HEPA filter that features a four-layer filtration system to capture 99.97% of particles in the air as small as 0.3 microns. The brand recommends replacing the filter at least once every six to eight months to ensure it continues to function properly.

Download the Smart Home Life app on your smartphone or tablet and you can adjust settings like timers, fan speed, and more without leaving your seat and even while you’re not home. This allows you to keep track of your home’s air quality at all times and makes it even more convenient to use than more basic models. It’s also compatible with other smart devices like Amazon Alexa and Google Assistant so you can activate voice commands.

Considering everything it has to offer, we aren’t shocked that over 600 shoppers have given this air purifier a five-star rating. One person said that it “literally absorbed all the smoke” from their home after a mishap in the kitchen, and another claimed their “allergies have basically disappeared” since using this machine.

“In my veterinary office, I have had the opportunity to firsthand see the benefits that this air purifier offers,” another reviewer wrote. “Through its ability to effectively eliminate smoke, dust, smells, and allergies that are linked with pets, it creates an atmosphere that is healthier for both the pets and the people who are involved with them. Extremely happy!”

The fact that you can score a $700 air purifier at such a low price is almost unheard of, so don’t hesitate to grab one before it’s too late.
