Airthereal starts the new decade with the Airthereal AGH550, making it the flagship of the company up until now. The next-gen model fixes many weaknesses of the previous models, while adding high-end specs to rivals the mid-range club. Could it present a curious blend of features that straddles the line between affordable and premium? Let’s find out in our Airthereal AGH550 Review.

Airthereal AGH550 Price

Users looking for a large room air purifier that fits relatively mid-range price tag, the Airthereal AGH550 is where you should be looking at. This air purifier is one of the first two new models last year by this American company, together with the Airthereal APH230C. Unlike its siblings, the Airthereal AGH550 is bigger, stronger so it plays its role in mid-range segment.

Airthereal also starts the new lineup with this Airthereal AGH550, called ‘Glory Days’. Now the ‘Pure Morning’ started with the famous Airthereal APH260 is just the past, and we can expect more models of this new lineup in a near future.

The Airthereal AGH550 certainly brings many new strength for the users, and it fixes most of the weaknesses from its predecessors, like the high power consumption or the difficulty in installing air filters. This air purifier has something similar to the Levoit LV-H133, as both devices are the first sample of the company to target mid-range segment.

Airthereal AGH550 has been priced at $299 officially on Airthereal website. The air purifier is available on Amazon as well, and thanks to our deal, you can find it at only $259 for a limited time.

While the Airthereal AGH550 is strictly a mid-range air purifier and a step in the right direction, it takes the fight to more premium air purifiers like Levoit LV-H134, Coway AP-1512HHS, Medify MA-40 and Honeywell HPA8350 among others. Having said that, does the Airthereal AGH550 come with enough firepower to take on the slightly more premium air purifier, we find out.

Airthereal AGH550 Design and Size

Right off the box, the Airthereal AGH550 follows strictly the winning design made by last year’s dominant air purifiers, like the Levoit LV-H134 or Winix NK105. Here we are another cylindrical tower air purifier, but it is quite smaller than these aforementioned devices, with the height of only 24.6 inches. In fact, it is even smaller than the GermGuardian AC9400W or Hathaspace Smart True HEPA Air Purifier 2.0.

It’s got a plastic build which feels very brushed with the onyx black and curves towards the sides making the Airthereal AGH550 not wholly a cylinder shape. Overall it is solid and firm on the ground, thanks to a flat base and balance in the design.

This air purifier also sports the normal bottom-to-top air flow system concept, with a 360° air intake. On the downside though, it uses a front plate rather than perforated holes for exact 360° inlet, and that’s a pity.

I’m quite curious of the shape of perforated holes from both air inlets of the Airthereal AGH550, then I find out that they are the symbols of horoscope. It seems Airthereal AGH550 is looking for a way to distinct itself from others. The idea is nice, however, and sometimes air purifier companies should let users be curious about their products like that.

This air purifier returns the high-quality touch control panel from the Airthereal APH260 and adds more colored readings. It makes the Airthereal AGH550 truly amazing, especially in the darkness.

It weighs around 14.7 lbs, which is surprisingly more lightweight than both Levoit LV-H133 and Levoit LV-H135. There are two handles from both sides, so you can move the devices easily in your home.

Airthereal AGH550 Filters

Normally, we will check the quality and quantity of the air filters to decide its performance, as well as the air filter types being used. Airthereal is well-known for their 7-in-1 HEPA filter, which is a high-end air filtration system on a budget. In this Airthereal AGH550, the company decided to push the limit a level beyond, even in a simple 3-layer air cleaning system.

1. Pre-filter – An aluminum mesh preliminary filter covers the True HEPA filter, to prolong the life time of the core filter, by trapping the large objects of pollutants like fur, hair and large dust. It is 100% recyclable.
2. True HEPA filter – With the True HEPA filter, this air purifier can capture 99.97% of as small as 0.3 microns allergens, virus particles, pollen, mold and fungi particles.
3. Activated Carbon filter – The real power of Airthereal air purifiers is inside the carbon filter, as a combination of Nano mineral, Cold catalyst, Photo catalyst and Molecular Sieve carbon. It will adsorb the odors, chemicals and smoke from the indoor air.

Airthereal AGH550 is another air purifier with 100% ozone-free from this company, hinting that Airthereal will only make air purifiers using mechanical filters from now on. It is a bold move, to guarantee no ozone emission from the ionizer, resulting in easy pass of the CARB certification.

For the latest flagship, Airthereal only uses the high-quality materials for its air filtration system. The pre-filter is now made of aluminum, to increase the resistance against the airborne impurities, and therefore is more durable.

The HEPA filter is thicker, made with thousands of layers of glass threads, which is the technology of high-end True HEPA filter in many famous air purifier brands. Airthereal AGH550 uses the glass HEPA filter to capture even particles with 0.1 microns in size.

Finally, we have an Activated Carbon filter attached with Nano mineral, Cold catalyst, Photo catalyst and Molecular Sieve carbon. This honeycombed carbon filter can adsorb and remove any types of odors, as well as be able to trap chemicals and Volatile Organic Compounds (VOCs).

If one reads specs carefully, they will know that Airthereal AGH550 is a tough opponent in mid-range segment. I made a test for this air purifier in an area of 300 square feet, and let it run for 1 hour. Also, I selected many other air purifiers to compare with it, like the Blueair Classic 280i, TruSens Z-3000, Vornado PCO375DC and Oreck Air Response Turbo. As a result, the Airthereal AGH550 was the winner with the highest efficiency of 99.92% for trapping any particles down to 0.3 microns, while it is the most affordable.

There is only one downside for the air filtration system of Airthereal AGH550. It can last for only 6 months, and the price tag of the new air filter is now $69. So the annual filter cost you need to pay for using this air purifier could be $140, which is quite high for a mid-range product.

Airthereal AGH550 Room Coverage

Airthereal AGH550 is powered by an EC motor, which combines AC and DC voltages with all of their advantages. As such, the air purifier can deliver stronger air flow, and the Airthereal AGH550 is suggested for up to 750 square feet by the manufacturer.

The ACH of Airthereal AGH550 is 4X. This is the common air changes per hour rating for air purifier, so it can clean your room every 15 minutes.

The CADR of Airthereal AGH550 is 290 Dust/ 295 Smoke/ 303 Pollen (cfm), which doubles the fan power of the Airthereal APH260. Airthereal sent this flagship to the AHAM for a certified test of CADR rating, to prove that it is truly powerful.

Airthereal AGH550 Sound

Armed with a powerful engine, the Airthereal AGH550 is surprisingly quiet. On lowest fan speed, the noise level is just 22 decibels (db), which is somehow like the rustling leaves’ sound.

In day-to-day performance, the highest noise level of Airthereal AGH550 is measured to be only 46 decibels. This could be the best air purifier for silent operation on highest speed, which even the Levoit LV-H134 or Blue Pure 121 can’t match.

If you want an air purifier with high performance in your bedroom, certainly the Airthereal AGH550 can meet all your requirements.

Airthereal AGH550 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 biggest disadvantage for using an Airthereal air purifier is high power consumption. However, Airthereal seems to find out a solution for this problem. The Airthereal AGH550 has a rated power of only 40 watts, which is a lot better than even the smaller Airthereal APH230C.

If you run the Airthereal AGH550 for 8 hours per day, it would cost you just $14 each year.

Airthereal AGH550 Additional Features

Airthereal AGH550 appears to be the flagship of this company up until now, so it is usual to see the top-class features inside it. For example, the Airthereal AGH550 makes use of a laser sensor, which is highly accurate than the previous dust sensor in Airthereal ADH80 and Airthereal APH260. It also delivers the report in air quality monitor for under 10 seconds, both in digital and colored readings.

Just like any air purifiers in Airthereal family, the flagship has a Sleep Mode, indicating its amazing ability to keep the noise down. For bedroom setting, you can use the Timer to schedule the time off, somewhere between 1 and 24 hours.

Simple child lock is another additional feature of Airthereal AGH550, to prevent the accidental changes of settings made by your children and pets. Finally, you have a LED indicator for filter replacement.

Our verdict

With all that power under the hood, the Airthereal AGH550 seems to be one of the best deals for mid-range segment. It doesn’t go overboard with too much power or smart features, but it is a solid option with the right specs in the right places. At the moment, the Airthereal flagship is something you can depend on to a certain extent, more so than every other air purifiers in large spaces and as I mentioned earlier, it has very low power consumption.

Certainly, there is so much to improve here and Airthereal just makes one air purifier for new segment, but the Airthereal AGH550 remains a great air purifier, and proves to be worthy with its name.
