Winix WAC9500 True HEPA Air Purifier Review

Winix WAC9500 True HEPA Air Purifier is made for a single room air purification up to 284 square feet (26 square meters).

This machine is also known as one of the best for pets. It has an excellent filtration system eliminating 99.97% of common airborne pollutants.

It also has excellent odor control presenting it as a great air purifier for anyone with asthma, allergies, or various chemical sensitivities.

Pros

  • Many great features include an auto mode, remote control, timer, sleep mode, etc.
  • Great multi-level air purification
  • Easy to operate and understand controls
  • Energy star qualified
  • One of the best prices versus air flow rate

Cons

  • Only one year limited warranty
  • PlasmaWave emits ozone. Luckily, you can turn it off.


Winix WAC9500 Design, size, placement

Winix WAC9500 has a simple design without any fancy elements. The machine is relatively large but not huge. It has an ergonomic design with an air inlet through the front panel and an air outlet through the machine’s top. 

A good screen with controls is on the front panel’s upper side. Behind the front display are filters and a fan. On the top is a remote control cradle.

Reviewing this 18.8lbs (8.5kg) heavy air purifier, I was surprised that it doesn’t have a carrying handle making it quite challenging to move it from one place to another.

Measurements:

  • Height: 22 in / 55 cm
  • Width: 16.5 in / 42 cm
  • Depth: 9 in / 22.5 cm

How it works and what sources of indoor pollution destroy

 

Winix WAC9500 True HEPA Air Purifier Review

Winix WAC9500 has multiple levels of filtration, making it a potent air purifier.

1. Antibacterial Pre-Filter

First, behind the front grill is the pre-filter. It catches the largest airborne particles such as pollen, hair, and dust. It helps to extend the life and efficiency of the HEPA filter.

2. True-HEPA Filter

Behind the pre-filter comes the True-HEPA filter. It captures 99.97% of particles as small as 0.3 microns, including pet dander, mold spores, and other small pollutants.

3. Nano-Silver Mesh Filter

The antimicrobial guard is made of tiny silver shreds. The Nano-silver mesh material presents excellent germ security, neutralizing bacteria in touch.

4. Carbon Filter

The last is the activated granular carbon filter. It is washable and is very powerful at catching and neutralizing strong, tough-to-remove odors, including ammonia, pet smell, organic decay, and cigarette smoke.

5. PlasmaWave Technology

Here my thoughts disagree with the manufacturer. As they say, this feature creates thousands of negatively and positively energized ions every second to create plasma clusters, instantly neutralizing chemical vapors, bacteria, odors, and gases in the air. 

You may say great, and why don’t you like such a great feature? My answer is ozone. The manufacturer says there is negligible ozone generated during the PlasmaWave process. 

Still, as I have tested, this feature doesn’t make many changes in the air, so I would suggest better keeping it turned off.

So this air purifier eliminates pollen, lint, hair, spores, mold, pet dander, dust mites, and most household dust and smoke particles. 

Reduces airborne bacteria and particles that carry viruses. Absorbs low odors and chemical vapors. That’s way better than competitors can do in this price range of air purifiers.


Winix WAC9500 FeaturesWinix WAC9500 True HEPA Air Purifier Review

Here comes the best part of this air machine. It has fantastic features, and you don’t overpay for them as this machine is one of the cheapest in its category.

  • The light sensor activates sleep mode when the room is darkened.
  • In sleep mode, the air purifier quietly uses the lowest fan speed. Also, the control panel lights will dim.
  • The filter change indicator will let you know when it’s time to change the complete filter cassette.
  • The timer allows adjusting performance to your choices.
  • Programmable and handy remote control. Operate within 20 feet of the air purifier; allows you to turn on and off the machine, plasma wave on/off button, timer button, sleep button, fan control, auto, and turbo buttons.
  • Smart Technology. Winix WAC9500 has sensors that detect light, odor, and dust and automatically set the fan speed according to what is required. With this technology, you can save cash because it doesn’t work any faster than it needs, saving electricity.

Manual operation also is possible. Pick between 4 fan speeds. 


Winix WAC9500 Noise Level

The lowest fan speed machine is quiet – you can easily sleep without problems. Middle speeds are quieter than a laptop fan. However, Turbo is quite loud as other air purifiers with powerful fans.


Winix WAC9500 CADR and Coverage Area

The CADR is 182 for dust, 183 for smoke, and 194 for pollen.

Winix WAC9500 can clean 275 square feet of large spaces 5 times per hour.

Bissell Air280 Max covers 280, Airdog X5 covers 270, and AirDoctor 2000 covers 244 square feet. So you might prefer these over Winix as they are newer models with more features.


 Winix WAC9500 Maintenance and upkeep

As with other electronic devices, clean it regularly with a dry, soft cloth.

Clean pre-filter and Nano-Silver Mesh/Carbon Filter every 3 months with normal use. The process isn’t complex and hard; follow the instructions from the user manual.

The filters can be washed up to 6 times without requiring replacement, but inspect them after every wash to guarantee they’re still in great condition.

Lightly vacuum the dust sensor every 2 months after removing the front panel.

Change the whole filter cassette when the indicator says. Normally it should be once per year. Please do not wash the HEPA filter; never attempt to remove it from the cassette frame.


Summary

Overall, Winix WAC9500 True HEPA Air Purifier is great; it has only a few insignificant cons. 

The pros are much more, including powerful and multi-level air filtering, smart technology with auto mode, remote control, and much more. 

This is one of the best single-room air purifiers in its price range. Highly recommended.
