Bigger and heavier than Winix 9300 at 16.5 x 21.9 x 8.9 in/ 18.8 lb, Winix 9500 is still the same old box-like air purifier design that is slightly outdated compare to the latest model. Whats good though its the detail front digital display that is thoughtfully added with clear indicator. Build quality is superb as excepted from this series of air purifier. Standard specification includes 5-stage filtration, the mentioned front digital display, trio Particle sensors (Dust, Odor, Light), 4 fanspeed with Auto mode and Sleep mode, filter replacement indicator, remote control, Ozone-safe certified by CARB, AHAM verified and ENERGY STAR rated.

With a bump up 284 sq. ft. purifying applicable area and 49 - 184 cfm airflow from Winix 9300, Winix 9500 offers greater but far from the best when it comes to air purification. Ideal for small to medium-sized bedroom or small living room if you maximize the fanspeed. Up to 4 selectable fanspeed starting from Low, Medium, High and Turbo. Addon from that is Auto mode where the fanspeed would be automatically adjusted based on the surrounding air quality and for night time, there is Sleep mode where the fanspeed would be set to low with dimmed indicator light. Both auto and sleep mode is powered by the particle sensors which comes with dust, light and odor sensor.

Undeniably Winix 9500 5-stage filtration is what the user would be looking for. Unlike the lower end series in Winix models, there is a standalone pre-filter that would capture first stage of large particles such as dust, fur and hair. Protected by the CleanCel Anti-Bacterial Treatment that stops any micro-organism from growing on the pre-filter. With larger particles cleared, the True-HEPA filter would be more effective in capturing down to 0.3 micron size particles with the rate of 99.97%. Odors and smoke from cigarette would be dealt with by the AOC Carbon Filter. Finally Winix PlasmaWave technology would help transform any airborne pollutants into safe molecule without emitting any harmful ozone in the process.

Driven by powerful 49 - 184 cfm airflow and wide 284 sq. ft. purifying coverage, Winix 9500 bundled Pre-filter True HEPA filter filtration is excellent in removing dust, pollen, mold, mildew, fungi and spores.  On tackling odors, smokes and fumes, Winix 9500 AOC Advanced Granular Carbon Filter is also excellent against chemicals, odors, cooking smell, fire, VOCs, tobacco smokes, cigarette, vapor, radon and ammonia.

Nothing spectacular on Winix 9500 5 - 70+ W power consumption and 26.6 - 60+ dB noise level as it is very identical to other Winix model at similar fanspeed. At low to medium fanspeed, there is a minimal fan sound that is bearable while at high/ turbo speed, a clear but not over-loud fan noise can be heard that might be everyone cup of tea. Energy consumption is decent at low to high fanspeed as Winix 9500 is ENERGY Star rated.

The challengers

Winix U300

Marginally better in purifying coverage, airflow distribution and CADR, the downside is the premium price tag and you have to do without a built-in timer.

Winix P300

Similar to above with superior airflow rate and coverage at a much lower price tag. You will have to do with a 3-stage filtration and without timer.

Austin Air Pet Machine

Stronger and better airflow distribution thus the extensive purifying coverage. Expensive and have to do without the air quality and odor indicator.

In conclusion......

  • Advanced 5-Stage PlasmaWave filtration with separate pre-filter and carbon filter.
  • A more efficient True-HEPA filter on small particles thanks to the pre-capture by the pre-filter.
  • Upgraded advanced Granular Carbon Filter that is more effective than regular Activated Carbon Filter found in lower series.
  • Both Anti-Bacterial Pre-Filter and Carbon Filter are washable.
  • 4 selectable fanspeed plus Auto mode that works well with the sensors.
  • Comes with the handy remote control.
  • Built-in timer with pre-set 1, 4, 8 hours off option.
  • Smart particle sensor that consist of dust, odor and even light detection.
  • Detail front digital display with separate indicator on dust air quality and odor level.
  • Only "1 year" warranty compared with other Winix Signature series air purifiers that offered up to 5 years.
  • Limited replacement filters as it is discontinued despite sharing the same filters as Winix 9500.
  • Improved but still far from the category best in CADR and purifying coverage given its price tag.
  • CleanCel Anti-Bacterial Treatment is not as useful as other filtration.

Where is Winix 9500 air purifier made from?

Winix 9500 air purifier is made and manufactured in South Korea.

What is the function of Air Quality Sensor with Auto-Mode?

Air quality sensor or particle sensor detects the level of harmful particles in its surrounding. Using the information collected from the AQ sensor, Auto-Mode would automatically adjust the ideal speed accordingly. That way you get the best of both worlds in performance and energy-efficiency. All Winix air purifiers come with air quality sensor and Auto mode.

Is Winix 9500 air purifier wall mountable?

No Winix 9500 is not wall mountable.

Does Winix 9500 comes with all the filters for this price or do we need to buy the filters separately?

By default, Winix 9500 comes bundled with all the filters required for the air purifier to work.

How do you clean the pre-filter?

Winix permanent pre-filter or specific carbon pre-filter can be wash through vacuuming or rinsing. Simply remove the front pre-filter from the air purifier and rinse it with water to clear out all dust particles. The pre-filter must be completely dry (air-dry or hair dryer) before installing back into the air purifier.

Should I vacuum Winix 9500's carbon filter or HEPA filter periodically to boost the filters lifespan and usability?

Other than the AOC filter that requires cleaning once every 3 months, there is no need to vacuum the carbon filter or true HEPA filter before replacing them as the filters would be protected by the pre-filter from having contact with larger particles like dust. Furthermore, improper conduct on the carbon or HEPA filter could have a reverse effect that damage the filters usability and re-release the trapped particles like allergens, germs and bacteria out. You would, however need to clean the permanent pre-filter periodically or every 14 days depending on how much dust is accumulated by the filter.

Is Winix 9500's True HEPA filter washable?

You should never wash or even vacuum Winix 9500's HEPA filter unless it is clearly stated in the instructional manual. HEPA is a type of mechanical filter made completely from thin fibers. The water flow from washing or rinsing would cause irreversible damage to the HEPA filter by pushing the gap between the fibers. With opened gaps between each fibers, the HEPA filter lose its efficiency allowing fine particles like allergens pass through the filter easily.

Where do I find Winix 9500 replacement filter?

You can find the replacement filter for Winix 9500 from their official website or at Amazon. Always refer to the instructional manual on the correct filter replacement code or through our product specification section.

Can you use an extension cord to power Winix 9500?

Yes you can use it on Winix 9500 air purifier as long as the extension cord is not damaged or overloaded from too many connected appliances that end up consuming more watts than the cord can take in.

When Auto mode is selected, sleep mode is enabled by default?

When Winix 9500 is in Auto mode, sleep mode will also automatically engage when the lights go out. You will have to manually select any of the speed to disable both auto mode and sleep mode.

More on Winix 9500 Ultimate Pet

Winix 9500 Ultimate Pet might not be the best-looking air purifier in the market especially if you compared with Winix own Signature and FresHome series. It has a rather short width with a long depth that you could still move around Winix 9500 Ultimate Pet although a built-in caster would be a great help. The electronic display is located at the front panel as oppose to the usual top, which enhance the readability in my books. Build quality is sturdy with air intake on both sides while air outtake is located at top. Like most Winix air purifier, there are no other color options available (at least for now). Equally vital, the functionality, build quality, durability and reliability of the air purifier is specifically what we will be looking at. Built with a solid base fitting that produces zero gap, Winix 9500 Ultimate Pet body framework is supremely installed from top to bottom that will block any gas from releasing out. Decent air purifier volume and dimension enables sufficient purifying airflow through the air input and out take; a essential feature that we highlighted hundred of times again.

Applicable area and airflow

Winix 9500 Ultimate Pet
Ideally Winix 9500 Ultimate Pet should be the best air purifier for all living room, but due to the moderate air purifying coverage at 26 m2 (284 ft2), it is better suits to a small living room or a bedroom. With its 5-stage filtration cleaning, WAC9500 airflow is sufficient for everyday use. Put next with fairly similar type challengers, it still has appropriate purifying coverage area. Expect very much the same in time to purify its surrounding in-house air quality. Staying with equally crucial airflow delivery acceleration, Winix 9500 Ultimate Pet marvellous purifying will produce decent amount of clean air through its PlasmaWave technology. To conclude, expect acceptable tier of purifying air circulation effectiveness and distribution in its collection.

Filters and filtration

Standard combination of filter coming from Winix series. First stage of the pre-filter filtration would contains large contaminants and at the same time enhances the lifespan of other filters. The HEPA Filter would impede airborne particles such as pollen, mold and pet dander from releasing out. The carbon filter will eliminate gases and odors coming from chemicals such as paint, detergents, voc and cigarette smoke. Last but not least the PlasmaWave technology will dissipate and break apart air-borne particles for easy filtering. In general, any kind of hazardous particles such as dust, mold, dust mite, mildew, fungus and pollen will be contained and wipe off with ease.

Noise level and power consumption

A pretty silent air purifier, Winix PlasmaWave WAC9500 will produces regular to minimal noise that will not hinder with your everyday life and is ideal to use throughout the night. If you do the comparison with other common household appliances, the air purifier noise level is still within a reasonable tier. Carrying on with the power consumption, Winix PlasmaWave WAC9500 power input is respectable for an everyday air purifier. You will not feel the pinch even the air purifier is operating on a consistent basis. Compared to parallel segment household appliances, the power input is still comparatively low in its range.

Final thoughts on Winix 9500 Ultimate Pet

Although the name might suggest Winix 9500 Ultimate Pet is a specific targeted air purifier, it is actually a very flexible, capable air purifier that inherits Winix famous 5-stage cleaning technologies. It is also loaded with useful and practical features such as timer, smart sensors and auto/ sleep mode. Most essentially, it is brilliant in trapping practically any contaminants from dust, pet dander, mold to gases and odors from cooking, tobacco smokes or chemicals. The downside would be the dull exterior and the limited 1 year of warranty. Because of that, I would rather go with U300 that comes with a 5 years warranty with only a slight increase in pricing.
