  • Product Overview

    Get the cleanest air you can create with the Winix FresHome P300 Air Purifier. This Winix FresHome series air cleaner purifies the air in mid-sized rooms up to 300 square feet. It uses an advanced 3-step filtration system that includes Winix's patented PlasmaWave purifying technology to thoroughly rid your air of symptom-triggering allergens and odors. Convenience features like an air quality sensor plus automatic mode and a check filter indicator help take the guesswork out of day-to-day use. It's great for bedrooms, dens, and any other mid-sized space and provides Energy Star-qualified efficiency to keep your operating costs in check.

    Advanced Multi-Stage Filtration

    Winix 3-stage air purification system

    The Winix P300 Air Cleaner features an advanced 3-step filtration system that removes the most aggravating indoor allergens before they trigger your allergies. This system includes:

    • Carbon Pre-Filter - Air initially passes through an activated carbon pre-filter that absorbs household odors and removes hair, lint, and other large particles. This filter also helps extend the life of the true HEPA filter, reducing your need for replacements.
    • True HEPA Filter - Next, air moves through a true HEPA filter that captures nearly 100% of microscopic allergen particles, including pollen, pet dander, mold spores, dust, smoke particles, and bacteria.
    • PlasmaWave Technology - As a final step, air is treated with Winix's patented PlasmaWave technology to remove airborne viruses, chemical vapors, gases, and remaining odors. The PlasmaWave system uses naturally formed hydroxyls to neutralize these airborne pollutants at the molecular level, rendering them harmless. The Winix P300 has increased flexibility with an option that lets you turn the PlasmaWave feature on and off.

    After air is thoroughly cleaned, it's released into your space with the help of a super-efficient yet whisper-quiet fan. Choose 1 of 4 speeds for greater control over clean air distribution. The lowest and quietest speed is great to use overnight while the highest speed purifies your space quicker.

    Air Quality Sensor Plus Auto Mode

    The Winix P300 Air Purifier features automated controls to take the guesswork and hassle out of cleaning your air. When running in automatic mode, an air quality sensor monitors the presence of airborne particles and adjusts the fan speed automatically. This ensures pollutants are filtered out quickly for clean air around the clock. These features also help the air purifier run more efficiently, which may reduce your operation costs.  

    Additional Features

    Winix FresHome P300 - AHAM-verifide

    • Electronic Controls - The Winix P300 features easy-to-use electronic controls with LED indicator lights and a color-coded air quality sensor.
    • Remote Control - Adjust the air purifier's settings comfortably from a distance with the full-featured remote control.
    • Filter Replacement Indicator - Always know when it's time to replace the filters with the convenient check filter indicator. This indicator works off actual filter usage versus a published filter schedule, so you only purchase filters when necessary.
    • Dimming Light Sensors - All the LED indicator lights can be dimmed for the overnight hours, so they won't disturb you while you sleep.  
    • Quiet Operation - On its lowest speed, the P300 operates at 26 decibels of sound - quieter than a whisper.
    • AHAM Certified - The P300's effectiveness is certified by the Association of Home Appliance Manufacturers (AHAM).
    • High CADR Scores - In testing, this model received high Clean Air Delivery Rate scores for its coverage area. These scores indicate its effectiveness in filtering out various pollutants: Dust - 197, Pollen - 214, and Smoke - 197.
    • Carrying Handle - Use the built-in carrying handle to move the unit around easily and get clean air anywhere in your home.
    • Ozone-Safe - PlasmaWave Technology is ozone-safe and complies with California Air Resources Board (CARB) regulations.
    • Energy Star-Qualified - Energy Star air purifiers are 40% more efficient than conventional models and can save you up to $25 annually on your operating costs.


    The Winix FresHome P300 Air Cleaner purifies mid-sized rooms and spaces with a 3-step filtration system that includes Winix's patented PlasmaWave technology.

    What Customers Love

    • Air Quality Sensor - The air quality sensor detects large concentrations of pollutants then automatically adjusts the purification speed with no intervention needed.
    • Long-Lasting Filters - Vacuum the carbon and HEPA filters clean to help them last longer and reduce your filter replacement costs.

    Things To Consider

    • Loud On High - Customers report that on its highest speed, the P300 is noisy at 55 decibels. This is comparable to a refrigerator "hum." The lowest speed is barely audible.

            Comments about Winix P300 FresHome HEPA Air Cleaner with PlasmaWave Technology:

            We put the unit in our living room with one wood stove and 6 dogs - up off the floor to avoid dog hair and reach the smoke better. It does a great job and best of all is quiet enough to leave it on all the time. I will buy another identical unit for our upstairs bedroom to catch the smoke that the downstairs unit misses. My only negative is that the controls on the remote are hard to do get used to them though and it is not a big problem. We have the unit UP on top of a large cabinet, close to the ceiling so we use the remote exclusively to operate the unit. I am very happy with my purchase - after buying and returning 3 other brands of air purifiers for excessive noise.

              Comments about Winix P300 FresHome HEPA Air Cleaner with PlasmaWave Technology:

              I ordered the small 150 Winix unit but was sent the P300 unit instead. I have had it for about four months. Although my purchase was for a very small office and I wanted a small size air cleaner, the P300 is only slightly larger than the 150 and, compared to the 150, has almost a third greater CADR ratings. In that very small windowless office I spend up to 7 hours a day talking one-on-one with clients (about 45 to 60 minutes per person). I wanted clean air with a quiet fan that would automatically increase air flow when odors were present. The Winix P300 did the trick. Its lowest fan speed setting is barely audible thus doesn't interfere with conversations or the hearing of hearing impaired clients. The cost was less than $200; filter costs/changes, not unreasonable. However, the BIG test for this unit came very recently (now!) when dry lightening struck our mountainous region causing 4 major "complex" wildfires. The fires are currently out-of-control (i.e. spreading) despite the 1000+ firefighters, helicopters, airplanes, and the National Guard. The fires will not likely be contained until October when we have rain (two more months). Outdoor air quality has been rated in the hazardous range periodically this past week. Thus, I took the Winix P300 home where it now sits in my bedroom (15 ft x 11.5 ft with an 8 to 12 ft slanted ceiling). Last night, as I was watching news about the fires on television in another room (where whole house air is filtered by two filters from a heat pump unit), my sinuses became stuffy, throat itchy and sore, and a headache began. I retreated to the bedroom, turned the Winix on high (not turbo) and within 20 minutes, I felt fine, again. Thus, even in these conditions, the Winix 300 does a "good enough" job to improve the quality of air! Thanks, Winix (and Sylvane)!


              Great unit.
