Winix P300 Air Purifier: Trusted Review & Specs

Winix P300 (Winix WACP300) is, of course, the upgrade of the previous Winix P150.

So you should check the Winix P300 Review to know if it is still the good air purifier to buy or not.

The Winix P300 is discontinued, so if you want a great performer at the same price point, you don’t need to find anywhere because the Winix AM90 is so great to be your best companion. Also the latest Winix 9800 is released, packing with more power.

Since 2003, Winix is not a strange name of air purifiers in the U.S. It is not a bluff to say the Winix is the best Asian air purifier brand in the U.S market right now, especially when others like Coway or Sharp don’t try to bring more of their air purifiers to expand market shares in the North America. Though being superseded by the Winix 9800, the Winix P300 is still a great air purifier to buy (if you can buy), given a much lower price from launching. Okay, it’s time for the Winix P300 Review.

Winix P300 Price

The Winix P300 doesn’t flatten the P150 model in every respect. It’s bigger but more comfortable to use, also with a much improved fan power and bigger True HEPA filter make it a worthwhile update.

Time has passed and the Winix P300 is likely to be replaced by the Winix U300, which is full of better filtration methods than the Winix P300.

The medium-room version Winix P300 has an imposing task ahead of it. To live up to expectations it needs to have better fan power, not to mention the bigger-size air filters to fit its body. I am, of course, comparing the Winix P300 with the previous Winix P150.

But Winix P300 is, therefore, an attempt that this Korean company only make for the sake of the new different appearance. You must be familiar with the trio of Winix 5300-2, Winix 5500-2 and Winix C535, which again are the different color options for a same machine. And the Winix P300 doesn’t contribute much if compared with these three air purifiers. I mean, they have similar air filtration process, as well as the same fan power.

So you will have here another option for average fan power, and the Winix P300 will cost you around $229 as stated in the official website. However, the Winix P300 has been discontinued.

For medium-room version of other brands, such as the AeraMax 200 or Honeywell HPA200, the price of Winix P300 is a bit higher. However, this air purifier has better fan power than the representative of AeraMax, and more comprehensive air filtration than the Honeywell HPA200. Our Winix P300 even has the better fan power than the Smart Philips 2000i and Medify MA-40, as well as a better price tag.

But the real champions in this budget realm are the Coway AP-1512HH, Airmega 230 and Levoit Vital 200S. While the Coway AP-1512HH is much more cost-saving in a long-term run, as well as having a magnificent performance; the Levoit Vital 200S is the real future of air purifier, with lots of amazing features. Even with a good fan base, the Winix P300 needs much more to persuade people to buy.

Winix P300 Design and Size

No matter which version of the Winix FresHome model you choose, you get the same core design. This Winix P300 is just the bigger Winix P150 by any means, like the same front plate to hide the air intake grill, a plastic body and of course, even the same control panel.

This is the first of the Winix FresHome family to have the remote control, so you don’t need to worry about the short size of this air purifier. In fact, it is 21.65 inches, but the width is nearly the same with only 16.3 inches, giving the Winix P300 a feeling to be much taller than the previous model. This is also the same dimension of many other Winix air purifiers, like the Winix 5300-2, Winix 5500-2 and Winix C535.

The Winix P300 uses the traditional bottom-to-top airflow system concept, with a bigger air outlet grill on top. You can easily find the similar concept in many air purifiers of other brands, like the Levoit LV-PUR131, AeraMax 300 and Honeywell HPA300. Moreover, with the air grills under the front plate, this Winix P300 can make use of the 360° air intake to improve the efficiency of pulling polluted air.

Also, the lean-on-front display control panel remains the same in this Winix P300.

Just like the Winix P150, we will only have a inconvenient handle to move this Winix P300. And the weight is heavier, as the Winix P300 is 14 lbs.

Winix P300 Filters

Winix P300 is not a budget air purifier anymore, and with the higher cost than the popular trio of Winix 5300-2, Winix 5500-2 and Winix C535, it is quite disappointing that the Winix P300 has only the old 3-stage air cleaning system.

1. Pre-filter – The polluted air must pass through a built-in pre-filter. This pre-filter will help capture the large objects of contaminants, such as pet hair and even some kinds of pet dander and skin. The pre-filter is also attached with an Activated Carbon filter to help reduce the pet odors and smoke, as well as some common household chemicals.
2. True HEPA filter – The True HEPA Filter that captures 99.97% of as small as 0.3 microns allergens, virus particles, pollen, mold and fungi particles.
3. Winix PlasmaWave – This technology is one kind of ionizer, which can further reduce the amount of pollutants. Can be switched on/off.

Of course, it is the same air filtration system as any air purifiers of this brand. Winix P300 has a mesh pre-filter attached by the carbon filter, to offer odor protection against household odors from cooking, pets and smoke. The next mechanical stage is the True HEPA filter to capture 99.97% of any airborne allergens including of pollen, mold spores, dust, pet dander, microbes and even small bacteria and viruses.

But the most important part is the PlasmaWave technology, as the Winix P300 is able to create hydroxyls to instantly neutralize bacteria, VOCs and gases. This technology is claimed to not emit ozone, and by combining the PlasmaWave with True HEPA filter, the Winix P300 offers the full guard and releases only the clean, fresh air for you.

Again, I put the Winix P300 into a small test for performance, with the conditions to be a large space of 200 square feet, and let the Winix P300 to run in 1 hour. I also used the Coway AP-1512HH, Oransi Finn, Sharp FP-F60UW and Honeywell HPA300 to compare with this today air purifier. Against too many strong opponents, the Winix P300 didn’t show any sign of inferiority, as the overall efficiency of trapping particles down to 0.3 microns is truly high, with 99.9%.

Of course the Winix P300 will have an even higher filter cost than the Winix P150, and it is also the filter replacement from the Winix 5300-2 and Winix 5500-2. For one year of use, you need to pay $79, and in the time of writing, the filter is on sale to be only $59. You should check the link below to know the actual price.

Winix P300 Room Coverage

The Winix P300 is truly a worthy upgrade from the small Winix P150, and it broadens the room coverage to 300 square feet. This is also the room coverage for the next-gen Winix U300.

The ACH of Winix P300 is 4X. This air purifier is ready to exchange the air every 15 minutes.

The CADR of Winix P300 is 197 Dust/ 197 Smoke/ 214 Pollen (cfm). The CADR rating of this Winix P300 is equal to even the mid-range air purifiers like the Rabbit Air BioGS 2.0 or Oransi Max, and you can believe that it is suitable for the room of 300 square feet completely.

Winix P300 Sound

Part of the attraction of the Winix P300 is its silent operation, which tends to continues the stability of its brothers, with a low noise level of only 28 decibels (dB). This air purifier is as silent as the whisper.

Winix is an air purifier brand with fame in making low noise level air purifiers. Even with a much more fan power, this company improves the fan to reduce the noise level as low as possible. This is also the effort Winix tries to do to reduce the ozone emission from its PlasmaWave technology.

If you plan to run this Winix P300 in your bedroom or your office, I believe that you won’t be distracted by the noise it makes.

Winix P300 Power Consumption

One of our most FAQs is “Do air purifiers use a lot of energy?” In fact, air purifier must be used for a long time to be efficient. And power consumption is one important criteria to review if this air purifier is good or not.

The Winix P300 has higher power consumption than the Winix P150, of course, it has higher fan power. But the power consumption of the Winix P300 is only 60 watts, and therefore is a lot better than the power consumption of the Winix 5300-2 or Winix 5500-2 with 70 watts. Again, you should remember the Winix P300 is an air purifier with Energy Star rating.

For using the Winix P300 8 hours per day, it would cost you only $22 per year.

Winix P300 Additional Features

The “Set and Forget” function of Winix P300, just like any other air purifiers of this brand, is all about the Smart Sensor and Auto Mode of this air purifier. With this function, the Winix P300 can automatically adjust the fan power to match the current indoor air quality. Though the sensor is only the odor sensor (accept it, even the Winix U300 has only the odor sensor), this Winix P300 is a necessary device to help you forget about any complicated control.

If you are fond of the Wi-Fi Enabled Connectivity feature, you should look for the Winix C545 and Winix AM90 instead, as they both offer this high-end feature while keeping the price to be nearly the same as the Winix P300.

Winix P300 can easily be controlled by the remote when you are far from this air purifier (only 20 ft from the air purifier). Moreover, when in the Auto Mode, this air purifier activates the light sensor, which can detect the amount of ambient light in the environment and automatically dims the control panel light and changes the fan speed to low.

And finally, you still have the LED indicator for filter replacement in this Winix P300.

Our verdict

Winix P300 has better power consumption than the trio of Winix 5300-2, Winix 5500-2 and Winix C535, but for a higher price what you will gain can’t compensate what you will lose. This air purifier has decent air filtration process, and if you want to have the best of Winix, you must go for the Winix U300.

Winix P300 has been discontinued, along with its brothers. However, you have the Winix AM90 with the same great performance and much better features.
