  • Product Overview

    Count on the Winix FresHome P450 Air Purifier for the cleanest air you can create in your home. Part of the new FresHome Series air cleaners, the P450 is Winix's largest and most powerful air purifier to date. It combines 3 advanced air cleaning technologies to capture virtually all the symptom-triggering allergens, chemicals, and odors polluting your indoor air. Plus, it's loaded with convenience features that simplify operation and make it easier than ever to breathe cleaner day after day. With a sleek and attractive design, the Winix P450 Air Purifier is ideal for your family room, living room, and other large areas in your home up to 450 square feet.

    Three-Stage Filtration

    Winix 3-stage air purification system

    The Winix P450 Air Cleaner features an advanced 3-step filtration system that removes the most aggravating indoor allergens. 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, dust, smoke, 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.

    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.

    Automatic Air Cleaning

    The Winix P450 Air Purifier features automated controls to take the guesswork and hassle out of cleaning your air unlike conventional air purifiers. In Auto 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. The air purifier also runs more efficiently, which helps keep your operating costs in check.  

    Additional Features

    Winix FresHome P450 - AHAM-verifide

    • Electronic Controls - The Winix P450 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 P450 operates at 27 decibels of sound - quieter than a whisper.

    • AHAM Certified - The P450'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 - 298, Pollen - 343, and Smoke - 291.

    • 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 P450 Air Cleaner cleans large rooms quickly and efficiently using a 3-stage filtration system and Winix's patented PlasmaWave technology.

    What Customers Love

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

    Things To Consider

    • Big Size - The P450 is Winix's largest air cleaner to date and fits best in large rooms and spaces.

        Comments about Winix P450 FresHome HEPA Air Cleaner with PlasmaWave Technology:

        Being allergy sufferers, we use high quality pleated hvac filters but it isnt enough. We both one for our bedroom and liked it so well, we bought two more. We now have two 450's for larger rooms and one 300 for a smaller room. We are well impressed with these units. We are hoping that they have as long a life as the blue air we replaced. Truly whisper quiet on the lowest setting and although louder on turbo, it is comparable to other units at medium speed.

          Comments about Winix P450 FresHome HEPA Air Cleaner with PlasmaWave Technology:

          We have used air filters and purifiers for quite a few years now. We have 3 competitor's units in our home currently and we use a high CADR rated pleated filters in our HVAC systems.
          We are allergy sufferers, live in a warm, damp climate and have Cavalier King Charles Spaniel dogs.
          We bought this unit as a replacement for a large master bedroom with high ceilings and fabric covered furniture. We especially need to keep dust at a minimum.

          I did quite a bit of research before choosing the Winix P450.
          I did not want a unit with a bulb or with a washable filter. We use these devices to keep dust, pollen and dander away from us and our respiratory tracks. I want to put the old filters in a bag and throw them away.
          i DID want an effective, true HEPA filter and a unit that was quieter than the previous Blue Air model we used. ( it died ).

          Straight out of the box and the Winix P450 went to work! Remove a few protective wrappers, plug it in and its working. It sets itself pretty automatically although you can adjust it very easily manually.

          it is QUIET! - virtually undetectable sound on auto! ( this unit is near my bed - I am a light sleeper! )

          It operates with your familiar charcoal pre-filter and a true HEPA filter, PLUS it has technology which removes airborne viruses, and odors. It is ozone safe.

          It is all digital and touch sensitive controls. VERY easy to adjust and operate. Soft lights dim for overnight hours.

          Very attractive, taller and QUIETER than my old air purifier unit. Even when it is on medium speed it is quieter than my other units on lowest speed.

          It is relatively slim and therefore easy to place in your room and seems to be less obtrusive than other brands.

          I am not easily impressed frequently but the Winix P450 has impressed me.
          Since I have owned it for a short time, I cannot comment on how long it will last in comparison to the other brands I have used.

          On a scale of 1-10, it gets and 11!

          When my other air purifiers die, I will replace them with Winix models.

              It is a new model. But You can not turn the plasmaWave off from the remote or main pannel. This is the only reason for me to return it for an older WAC9500.
