This is a medium-large unit. It is 23.6 inches high, 9.6 inches wide, and has a length of 16.3 inches. It weighs around 19 lbs. The air goes through the front side and comes out from the top.

So, place it somewhere that doesn’t block these sides. This unit is portable but keeping the weight in mind, you should use it where you spend most of your time.


The noise level on this unit is not much. Out of 4 fan settings (low, medium, high, turbo), you get around 28 dB at the low fan speed. At max speed, you get around 55 dB. Apart from these fan settings, you also get a sleep mode with the lowest sound of 25 dB.

You can comfortably use the unit in your bedroom by turning on the sleep mode. It will set the fan speed to the lowest and put out all the lights so that you get an uninterrupted good night’s sleep.


The unit can cover up to 300 sq. ft. according to AHAM verification. User reviews suggest it can cover almost twice the coverage area mentioned. You can use it in a 500 sq. ft. room and will get similar results of a 300 sq. ft. room.

The ultimate pet purifier is absolutely wonderful. It has a strong 5 stages purification system. First, the air goes through the ultimate pet filter that specifically targets pet hair, fur, and dander. This filter is replaceable.

Then washable mesh pre-filter then captures larger particles and passes the air through Advanced Odor Control (AOC™) washable carbon filter.

It captures 99.97% pollutants, germs, viruses, bacteria, mold, pollen, etc. The filter is replaceable and recommended to change every 12 months.

Finally, the purified air goes through the PlasmaWave. This technology breaks down odors, allergens, chemicals, and other pollutants to the molecular level and cleans the indoor air. The manufacturer claims this process doesn’t produce harmful OZONE.
