Let’s discuss this filterless air purifier in more detail. First, we will talk about the design and move on to its build quality, performance, and price/value. At the end of the review, we will give you the verdict of whether or not this air treatment system is worth your dollars.
The Pionair 1500 is a compact unit. It measures 5.5 x 4 x 10.8 inches, which is incredibly tiny considering it is rated for 1500 square feet. It is also lightweight at only 3.3 pounds. You can put this unit on top of the fridge or bookshelf with no worries. Moving it around from room to room won’t put a strain on your arms and back too.
While the truncated pyramid design looks simple it also looks sophisticated. The power button is hidden on the backside while front side only displays the vents. Everything about this unit is operated using that single power button on the back. Truly a no-fuss design.
Since there is no built-in fan, the Pionair 1500 works in complete silence. Being filterless, you are exempted from the task of cleaning and replacing filters regularly.
Pionair gives you 3-year manufacturer warranty that covers both parts and labor. That shows how confident Pionair is about their product. The fact that some users have been using the same unit for ten years is also another proof of the excellent build quality of the Pionair 1500.
The lack of a fan or any moving parts like those you usually find in a filter air purifier means there are fewer points of failures in this unit. That’s an important point since this unit is portable and some people take their units with them while traveling.
This unit purifies the air in four ways: UV sanitizer, Photo Catalytic Oxidation (PCO), negative ions, and ozone.
The UV lamp module in this unit generates UV-C light whose wavelength falls in the 100-280 nanometers range. The powerful ray is considered germicidal as it penetrates the wall of viruses, bacteria, mold, mildew, and fungi and destroys their DNA or RNA.
“But UV rays cause cancer!”
Yes, long exposure to UV rays can give you cancer, but you’re not sitting close in front of the unit, right? In real-life conditions, your exposure to UV light while walking outside will be considerably higher than what you get from the air purifier.
If you’re still doubtful about the effectiveness of UV light against bacteria, watch the following short time-lapse video.
Photo Catalytic Oxidation (PCO)
The UV light emitted at a specific wavelength hits the Titanium Oxide plate inside the unit. This process generates super-oxide ions and hydroxyl radicals. These highly reactive particles combine themselves with pollutant particles in the air including bacteria and Volatile Organic Compounds (VOCs).
The following chemical reaction breaks the pollutant into harmless particles allowing you to breathe non-toxic air into your lungs
The Pionair 1500’s ability to take care of VOCs sets it apart with most commercially-available air purifiers. Most of them only handle allergens. To tackle VOCs, you need do extra work by planting some common houseplants such as the Snake Plant, Dracaena, Boston Fern, or Bamboo Palm.
“Are VOCs common in homes?”
Yes, they are. Ten commonly found VOCs in homes are acetone, benzene, butanal, carbon disulfide, dichlorobenzene, ethanol, formaldehyde, terpenes, toluene, and xylene. Those nasty stuff come from things like cleaning supplies, nail polish remover, wallpaper, mothballs, deodorizers, paint, detergents, carpeting, burning candles, car emissions, and plastics.
Suffice to say that any modern home will have VOCs lingering around. Those VOCs can do serious damage to your health. You’ll be thankful to have the Pionair 1500 around to turn those harmful VOCs into harmless substances.
As far as odor removal goes, this unit also excels. Once the odor-causing particles are oxidized, they no longer give off that foul odor you despise so much.
This unit gets rid of airborne allergens through a process called agglomeration. It releases negative ions that attached themselves to positively charged airborne particles. This process weighs down those particles allowing gravity to pull them down.
Ozone has been used by food processing industries as a mean of sterilization and now it makes its way to home appliances. Ozone is very effective against bacteria. It kills bacteria by destroying their cell walls. Once the wall can no longer keep its shape, the bacteria die.
This unit generates a no more than 0.04 parts-per-million (ppm) of Ozone. In actual home setup, the measured Ozone level will most likely hover in the 0.01 ppm.
The hefty price tag of the Pionair 1500 could really scare off some people. You, however, need to take into account that this is not a filter air purifier. There’s no filter to replace every three or six months. You only need to replace one light module once a year. That’s going to cost you fifty cents a day, though.
If you need an air purifier for an extra-large living space, the Pionair 1500 still makes a compelling choice. The fact that it handles VOCs while most air purifiers in the market don’t, should be accounted for.

The Pionair 1500 is a great addition to your home if you wish to win the battle against allergen, mold, pollen, dander, smoke, and bad odor. Not many filterless air purifiers can brag about utilizing four different air purification methods. You may say the 1500 is a good candidate for the best air purifier with UV light, but truthfully, it offers so much more in a compact design.
While the price tag could be a deal-breaker, you also need to take into account that this is a very low-maintenance unit covered with a 3-year warranty. So when you’re shopping for an air purifier that can cover your whole home, remember to put this on in your shortlist.
