It’s held back by dated design, but impressive performance means power users might just love it. Okay, let’s get back to Aprilaire Allergy+Pet9550 Review.

Other Aprilaire’s Air Purifier Reviews: 

Aprilaire Allergy+Pet9550 Price

As ever, the Aprilaire Allergy+Pet9550 was far cooler than any previous air purifier from 9550 series. It fulfills the Aprilaire image perfectly: a solid powerful air purifier with little to get excited about.

Highlights are only in the filtration system, and apart from that, you get a mere Aprilaire Clean9550 for the appearance.

The Aprilaire Allergy+Pet9550 costs the same as the Aprilaire Allergy9550, to be $599, but I rarely found a discount on it like its brothers. At the time of writing, there is a 65% OFF deal for this air purifier, but you should grab quickly because it won’t be here forever.

That price pits it directly against well-reviewed air purifiers including the flagships Alen BreatheSmart 75i, Rabbit Air MinusA2 or Medify MA-112. Plus there are Dyson Pure Hot+Cool, Dyson Pure Cool Link and Dyson Pure Cool Tower with excellent cooling and heating features, something that the Aprilaire Allergy+Pet doesn’t have.

Aprilaire Allergy+Pet9550 Design and Size

Again, I must repeat, the Aprilaire Allergy+Pet9550 is nearly identical to the Aprilaire Clean9550 and Aprilaire Allergy9550 in most sections. For the design concept, they are all the same.

Aprilaire Allergy+Pet9550 has a height of 27.5 inches and a width of 17.25 inches. The air purifier comes with rectangular prism shape, with handles from both sides.

The front cover can be removed by pulling away from the body, as it uses magnet to attach with. To make the device more beautiful, Aprilaire placed the air quality indicator right on top to be the main focus.

Aprilaire Allergy+Pet9550 uses a bottom-to-top air cleaning system, using the air intake from both sides, then it release the fresh air from top air outlet. Above the air outlet, we can find the control panel with electronic buttons as below.

For the weight, Aprilaire Allergy+Pet9550 is 26 lbs. You really need these two handles to move it around your home.

Aprilaire Allergy+Pet9550 Filters

Being the flagship of Aprilaire, the Aprilaire Allergy+Pet9550 uses the unique 4-stage air cleaning system, which is the ultimate filtration system of the company.

  1. Pre-filter – Captures large to medium airborne particles like large dust, lint, pet hair and fur. It can be cleaned by vacuum, or be washed to remove buildup.
  2. Pet filter – The special fine pet hair and dander trap can reduce the airborne particles (mainly pet hair & dander). It’s easy to clean, reusable and can provide extra protection for the True HEPA filter.
  3. True HEPA filter – Aprilaire Allergy+Pet9550 uses a True HEPA filter, which removes 99.97% of airborne particles as small as 0.3 microns like dust, pollen, mold spores, germs and other pollutants.
  4. Activated Carbon filter – Reduces household odors, VOCs and gaseous pollutants.

With double pre-filtration, the True HEPA filter from Aprilaire Allergy+Pet can easily last for one year, which is much more economical than the Aprilaire Allergy9550. It is highly recommended to buy for families with pets indoors.

I made the same test for the Aprilaire Allergy+Pet9550 like its brothers, in a room of 300 square feet and under 1 hour. As you can see, the Aprilaire Allergy+Pet9550 truly deserves the title of flagship, as it had the highest efficiency of trapping any particles down to 0.3 microns, at 99.95%.

Of course, you must pay more for the filter replacement, but it is mostly guaranteed to last longer.

Aprilaire Allergy+Pet9550 Room Coverage

Like all of its predecessors, the Aprilaire Allergy+Pet9550 is suggested to use in a room of 495 square feet.

The ACH of Aprilaire Allergy+Pet9550 is 5X. It will exchange the air in your room every 12 minutes.

The CADR of Aprilaire Allergy+Pet9550 is 320 cfm in general, which is a lot better than the Oransi Max and Rabbit Air MinusA2 in terms of fan power. However, its performance is a bit behind the Oransi mod.

Aprilaire Allergy+Pet9550 Sound

The Aprilaire Allergy+Pet9550 uses a lot of fan power, which results in higher noise level as well.

I measured the noise level to be 64 decibels (db) on highest speed, and with such noise, you can’t sleep easily.

To solve this problem, you should turn to Sleep Mode, which has a noise level of only 30 decibels. It is just like the whisper, and basically you can’t notice any sound from the device.

Aprilaire Allergy+Pet9550 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 Aprilaire Allergy+Pet9550 is 85 watts, and it doesn’t have the Energy Star rating.

If you run the Aprilaire Allergy+Pet9550 for 8 hours each day, you need to pay $30 each year.

Aprilaire Allergy+Pet9550 Additional Features

All air purifiers under 9550 Series, including of the Aprilaire Allergy+Pet9550, are the best air purifiers this company can deliver. They all pack with the Smart Sensor, an ability to detect the changes of indoor air quality, then adjust the fan automatically based on environment’s need.

We have a Turbo Mode in addition to the basic 3 fan speeds, to maximize the fan speed. Also, there is a Sleep Mode, which dims the light automatically, sets the fan speed to low and turns on a Timer for 8 hours. Thanks to the light sensor, the Sleep Mode will turn on automatically if there’s no ambient light.

There is a Control Panel Lock function, to prevent others change the current setting on this air purifier.

Finally, we will have a LED indicator for filter replacement. Whenever the filter cartridge is at 90% of its capacity, the air purifier will beep 3 times to notify you when the power is on. Also, the LED indicator will flash until you get a filter replacement.
