Do you like having an air purifier developed by NASA? If your answer is yes, prepare to spend for a high-range device, as Airocide is the only brand you can look for. Since 2007, the company has manufactured the air purifier with PCO technology – an air filtration system that can actual “destroy” the ultra-fine particles. The Airocide APS-300 is currently the top model of the NASA-funded company, and our Airocide APS-300 Review will give out every spec of this innovative air purifier.

Airocide APS-300 Price

The Airocide APS-300 was the flagship that Airocide had ever created, until the new guard name Airocide APS-1000 is released. But it saves the appealing design from the old Airocide APS-200 and Airocide APS-200 PM 2.5, something that we remember about Airocide.

It also dominates your pocket with the price. The Airocide APS-300 at launch was only behind its brother APS-200 PM 2.5, but thanks to the advanced technology, it keeps the price of $999 up until now. Meanwhile, its brother can be found with only $899 in some retailers.

For those who crave newer solution of air filtration, rather than the old-styled HEPA filter, the expensive Airocide APS-300 is the welcome addition to Airocide’s lineup. On the market, you can search for the Molekule Air and Molekule Air Pro with their PECO system, but I believe the original PCO air filtration system is better for stable performance.

Airocide APS-300 is very expensive, and it is more expensive than a lot of well-known air purifiers on the market, like Blueair Classic 680i, Airpura UV600 J120 or IQAir HealthPro Plus. It is nearly the price of the IQAir GC MultiGas, Boneco H680 or AeraMax Professional 3. Well, that’s the money you spend for premium devices.

Airocide APS-300 Design and Size

Airocide’s line up of the Airocide APS-300, APS-200 PM 2.5 and APS-200 seems to be just different color options. If you used the APS-200 from 2013, you will be familiar with most of the design language here. It’s actually quite difficult to tell the Airocide APS-300 apart from the rest of the family, but that’s not an issue as that was a great-looking device.

By saying that it was a great-looking device, this design of Airocide APS-300 was awarded Gold for Design and Innovation by Edison Award, in 2014. It brings a newer orange color, together with a neutral white color. Airocide APS-300 still uses the same premium woodgrain sleeve for the appearance.

Other specs remain the same. The Airocide APS-300 measures 18.7 x 6.9 x 6 inches and weighs 9 lbs, making it blend easily into any decorations.

It’s also important to note that the Airocide APS-300 uses an unique air flow system concept. The air flow direction comes from both top and bottom grills, then releases from the inlet inside the air purifier.

You can find the control panel inside the air purifier, as well as the power button from the back.

Airocide APS-300 Filters

Airocide APS-300 keeps the air filtration system from the first Airocide air purifier, but its internal part is upgraded for longer life time.

  1. PCO chamber – The advanced PCO technology made by Airocide APS-300 is able to eliminate virtually 100% of harmful pathogens and other allergens like mold, viruses, bacteria and Volatile Organic Compounds (VOCs).

The PCO technology is again implemented in this Airocide APS-300, to destroy even the tiniest pollutants. Refined by NASA itself, the PCO technology can convert damaging molds, microorganisms, dangerous pathogens, destructive VOCs and biological gasses into harmless water vapor.

In depth, the PCO technology is a chamber with hollow glass tubes, which are coated with a catalyst. Using UV light (254-nm light), the catalyst makes a chemical process called Photo Catalytic Oxidation (PCO), as it creates hydroxyl radicals (OH) and steals atom from the neighboring molecules (airborne pollutants), thus destroying the pollutants in the process.

The byproducts of this process is normally carbon dioxide (CO2) and water molecules (H2O). Airocide APS-300 is supposed to emit no ozone, though it isn’t certified by the California Air Resources Board (CARB).

At the moment, I don’t know how to get the filter replacement for the Airocide APS-300. The company told us that the chamber kit can last for 15 months, which is 25% longer than the current chamber kit of Airocide APS-200.

Airocide APS-300 Room Coverage

The Airocide APS-300 comes with a better fan power than the previous Airocide APS-200 and Airocide APS-200 PM 2.5. However, the air purifier is built to run 24/7, so it can clean a very large room. In my opinion, the most suitable room coverage for this air purifier is only room size of 300 square feet.

The ACH of Airocide APS-300 is 1X. It can exchange the air only once per hour.

The CADR of Airocide APS-300 is measured to be only 40 cfm. That’s why the air purifier needs to run 24/7 for constant performance. In fact, it fails our test at Breathe Quality, and we ranked this air purifier at D- for performance.

Airocide APS-300 Sound

Airocide APS-300 is virtually running with no sound on low mode, and the noise level is only 24 decibels (db). You won’t notice any sound when this air purifier is running on this mode.

It is also better than the previous Airocide APS-200 PM 2.5 on highest speed, as the sound level is only 55 decibels. It is similar to the white noise of a floor fan, and for some people, the white noise is necessary to help sleep easier.

Airocide APS-300 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 power consumption of Airocide APS-300 is just 40 watts on low speed, and 60 watts on highest speed. It is low, but its actual CADR per watt is terrible.

If you run the Airocide APS-300 for at least 8 hours per day, it would cost you $14 to $21 each year.

Airocide APS-300 Additional Features

Like all Airocide air purifiers in the family, the Airocide APS-300 can automatically change the fan speed based on the daytime or nighttime. Its Auto Mode can sense light, and respond accordingly to the suitable time.

There is one LED indicator for chamber replacement, to remind you when you need to change the chamber kit. So keep an eye for the blinking LED, to always keep your air purifier at peak performance.

Our verdict

While the Airocide APS-300 is obviously better than the previous Airocide APS-200, it is more expensive for nearly the same performance. Unless if you really like the white color option, or if you don’t care much on the spending money for new technology, the Airocide APS-300 isn’t the best answer.

Also, I must say it again that I can’t recommend this air purifier.
