Since 1954, Aprilaire has been the leader in making air purifiers for the North American, most notable with their whole-home air cleaners. However, the Aprilaire Allergy9550 shows that they can also make great consumer’s room air purifiers as well. Today, we will check the specs of this air purifier in Aprilaire Allergy9550 Review.

Aprilaire Allergy9550 Price

The Aprilaire Allergy9550 mixes excellent specs with current familiar but acceptable design to effortlessly claim the title of best Aprilaire air purifier to date. However, since the release of the Aprilaire Allergy+Pet9550 with the same price, maybe it is now the second-best.

While the Aprilaire Allergy9500 is just the upgrade for performance from the Aprilaire Clean9550, it is necessary for an air purifier under mid-range segment to have the highest rate of performance.

That’s a good thing, because at $499, Aprilaire Allergy9550 needs the sheer strength of specs to compete with the likes of the AIRMEGA 400S, Medify MA-112 or Alen BreatheSmart 75i. The Aprilaire Allergy9550 also looks quite similar to the Honeywell HPA600B, however it doesn’t have as many as smart features like the Honeywell counterpart.

Luckily, thanks to our deal, you can get the Aprilaire Allergy9550 for as low as $376, but you should grab the deal as soon as possible.

And don’t forget about any of these Dyson Pure Hot+Cool, Dyson Pure Cool Link and Dyson Pure Cool Tower, as they are quite… different from other air purifiers with cooling and heating features, while keeping the price as competitive.

Aprilaire Allergy9550 Design and Size

For most parts, the Aprilaire Allergy9550 is exactly like the Aprilaire Clean9550 and Aprilaire Allergy+Pet9550.

That means it keeps the dimensions of 27.5 inches in height and 17.25 inches in width. You’ll also find the similar rectangular prism shape for the console air purifier.

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 Allergy9550 uses a bottom-to-top air cleaning system, using the air intake from both sides. The polluted air will go from there, and release as the fresh air from the top air outlet.

On top, you will find the control panel, which uses electronic buttons to function.

Aprilaire Allergy9550 Filters

Aprilaire Allergy9550 uses the same 3-stage air cleaning system as the Aprilaire Clean9550, but it has a very important change inside the system.

  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. True HEPA filter – Aprilaire Allergy9550 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.
  3. Activated Carbon filter – Reduces household odors, VOCs and gaseous pollutants.

Thanks to the True HEPA filter, the efficiency of trapping ultra-fine pollutants has increased significantly. I made the same test for the Aprilaire Allergy9550 as the predecessor, and you can see the difference clearly. It can trap 99.93% of any particles down to 0.3 microns, in just 1 hour.

Though it uses the True HEPA filter, you still need to replace the filter after 6 months or at maximum, 12 months.

Aprilaire Allergy9550 Room Coverage

Aprilaire Allergy9550 is an air purifier for medium to large rooms, so the manufacturer suggests to use it in a room of 495 square feet.

The ACH of Aprilaire Allergy9550 is 5X. It will exchange the air in your room every 12 minutes.

The CADR of Aprilaire Allergy9550 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 Allergy9550 Sound

Higher fan power results in the higher noise level, and the Aprilaire Allergy9550 is not exception.

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 Allergy9550 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 Allergy9550 is 85 watts, and it doesn’t have the Energy Star rating.

If you run the Aprilaire Allergy9550 for 8 hours each day, you need to pay $30 each year.

Aprilaire Allergy9550 Additional Features

All air purifiers under 9550 Series, including of the Aprilaire Allergy9550, 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.
