Questions & Answers

How often do you have to replace the filter and what is the filter cost?
ByMay 5, 2024

Answer This Question

Cost $200. The machine will tell you when the filter needs replacement; it will depend on the environment the filter is in. You might be able to vacuum it once or twice before replacing....

      I'm obsessed with my Airmega ProX air purifier - it's been a total game-changer for my two-story home's air quality! 🌿💨. My home is an open two floors plan and I placed it on the 2nd floors open entry way so the air purifier is picking up airflow on first and 2nd floors. I'm so happy that I invested in a great air purifier at a sale price. A very happy customer. I'm waiting on a another big sale event to get another Airmega ProX for a great price. 🙌🙌🙌

      Received a used one with strawberry popsicle residue on top of it.
      I was so excited about this product. They sent me a used one. First, it was not properly packaged. There were zero styrofoam on each side of it. and when i opened it there was some kind of sticky substance on top of it. It smelled like some kind of strawberry popsicle residue. I am returning it.

      Thank you so much for bringing this to our attention, and we're truly sorry to hear about your experience. It’s understandably disappointing to receive a product in such condition—especially when you were looking forward to it.
      We’re currently working with Walmart to prevent third-party sellers from linking non-authentic or used items to our product page. Your feedback helps us continue improving this process.
      To help ensure you receive an authentic, brand-new item in the future, we recommend double-checking the “Sold and shipped by” section before purchasing. For genuine products, it should show Coway USA, Walmart, or occasionally Sylvane—never a third-party seller or unfamiliar company name.
      If this order was placed through one of our approved retailers and you still encountered issues, please don't hesitate to reach out to Walmart’s customer service or contact our own support team. We want to make this right for you.
      Thanks again for your honest review and for giving ProX a try—we hope to earn your trust back.

        Life is better
        Our new air purifier is life changing to the point that we bought one for our home and one for each of our daughters who live in different cities. The air feels and smells much fresher and helps me deal with my cat allergy at our daughter’s home.

        Awesome air purifier that is worth every penny!
        Have had this now for about a month. There is an initial smell to the filters that last about a day. After that you smell nothing. The unit is so quiet on the lowest setting you would not even know it is on. On high, I can put a small piece of paper on the fan output and watch it propel it more than two stories into the air. I love it and our air has never been better!

          Best Business Air Filter on the Market!
          [This review was collected as part of a promotion.] We have been using the Airmega ProX in our small medical private practice office. This filter is highly effective and not only does it do a great job at filtering air, it gives you details. The display has various modes and power cycles to fit the time of date and level of movement. The part that we have particularly found useful has beem the PPM numerical indication, letting us know how many contaminants the sensor has found in our air. Once the sensor detects any particulates it begins to increase filtration and you are able to see a change in the color on the dot on the right side of display. For purposes of showing how effective this was for us we started the machine (first picture), then we sprayed one of the various room fresheners we had. The machine immediately detected the spray, moved the color of the indicatior light to red, and displayed 49ppm as the level of contaminants in the air. For any small to mid size business this should be a must have. I know that all of our staff and patients all feel that this device is very effective and reliable and they are amazed at the accuracy of the sensor. Recommend to all business owners, its one of those necessary items every office should have!

            Great investment
            I bought an Aimega ProX for my art studio, and I’m extremely satisfied with the purchase. The air quality has improved and the free particulates are down considerably. If you’re an artist considering buying one, do it!

            Perfect Machine
            This machine handles my 3500 sq ft open floor plan farm house with ease. I love the light sensor that puts it in sleep/silent mode at night. When it wakes up in the morning it gets right to work. Even on turbo it isn't obnoxiously loud. The air quality sensor is great too. Have really seen it respond with the wildfire smoke we have in MI. We set it on auto and it ramps up when we go in or out of the house. Settles back down to 1 or 2 after about 20 minutes. Doing its job beautifully. Wish the filters would go on sale!
