When the AllerAir AirMed 3 doubles the filtration capacity in its carbon canister, the idea of maintaining an AllerAir 4000 (AllerAir AirMedic Pro 4) seems redundant. As the result, we can’t find the AllerAir 4000 anywhere on the company website now. But is it still good to buy? Let’s check our AllerAir 4000 Review to know more.
In Breathe Quality, we have reviewed all air purifiers under these sections. Also, we guarantee that:
- We do give honest reviews (both pros and cons) so anyone will guarantee to have the wisest choices.
- We do not (and never) exaggerate one product just to let you click the links and buy that product blindly.
- Good overall performance
- Solid built
- No Smart Features
- Lower performance than AllerAir 5000
- A bit unnecessary
AllerAir has been the closest competitor to Austin Air in the United States market, but unlike the New York counterpart, this company divides their core products into 3 different sizes, as well as 3 different prices. The AllerAir 4000 is the smallest of the three, and for some reasons we will tell you later, it is completely removed from AllerAir website. Okay, it’s time for AllerAir 4000 Review.

AllerAir 4000 Price
In many AllerAir big-bucks brand campaign in the past, they tried to give the AllerAir 4000 as the budget option to the AllerAir 5000, and sure many big brands always do that. The IQAir HealthPro Compact and Oransi EJ120 are the perfect examples of this trend, and of course, they don’t need much flagship identity.
Then the AllerAir 5000 got a down in the price, due to the new existence of the AllerAir 6000, and many of us can predict the end of this AllerAir 4000 Series. You still can find the air purifier on Amazon, but the price is varied from different sellers, starting at $599.
The AllerAir 4000 is once the main competitor of the Austin Air HealthMate, Medify MA-112 and Austin Air Allergy Machine. The Airpura H600 can also be considered as another challenger to this AllerAir 4000, especially when both brands are widely popular in Canada, too.

AllerAir 4000 Design and Size
The AllerAir 4000 looks like a smaller AllerAir 5000 on the outside, and it’s seen as the natural state for air purifiers. The Austin Air has shaped the design concept since 1990, and though many air purifier brands have developed at the moment, we still value this classic high-end air purifier design.
For those upgrading from the previous AllerAir AirMed, you will notice instantly the AllerAir 4000 is a lot heavier than your current air purifier. The height is about 17.5 inches, but the weight of this air purifier is 38 lbs, which as heavy as double the AllerAir AirMed 3. Luckily, we will have four casters to help move this air purifier anywhere in your home.
Other than that, we still have a 360° air distribution system in this AllerAir 4000, and the polluted air comes from the whole body of this air purifier, and releases on the top air outlet. Somehow the air flow system concept is quite similar to the Airpura.
AllerAir 4000 has a simple knob to change the fan speed setting, just like its brothers.

AllerAir 4000 Filters
One of the many main reasons to buy an air purifier from AllerAir, Austin Air or Airpura is the top-notch quality of their air filtration systems. This AllerAir 4000 is really powerful with the 4-stage air cleaning system as below.
- Pre-filter – First, we will have a poly pre-filter to capture large particles and prevent the main filters from clogging with pollutants. The pre-filter is necessary to extend the life of the main filters, and you need to change it every 3 months.
- True HEPA filter – The AllerAir 4000 uses a True HEPA filter to remove fine airborne particulates, with high efficiency of 99.97% for any particles down to 0.3 microns.
- Activated Carbon Filter – The high-quality Activated Carbon filter, either of virgin coconut (Exec) or virgin bituminous coal (Vocarb) to deal with chemicals, gases and odors.
- UV-C light filter – You can optionally choose the UV-C light bulb, to neutralize biological contaminates with ease.
It’s tricky that the AllerAir 4000 only has a 2-inch depth of Activated Carbon filter, which is slightly thinner than the 3-inch filter of AllerAir AirMed 3. It only holds 9 to 12 lbs of carbon in its canister, and I believe the adsorption performance of the AllerAir 4000 is a lot lower than the Supreme version of AirMed 3.
So that’s the second reason to delete the AllerAir 4000. Its performance is not the same as AllerAir 5000, and you can’t upgrade to the AirMedic Pro 5 with this small body.
But let’s see on the bright side, the AllerAir 4000 is still powerful with the core True HEPA filter from AllerAir. As advertisement, the filter is far more efficient than either Honeywell or Rabbit Air. However, the test didn’t show which pollutants are reduced in the testing process.
To help our audiences, I made a high-range test for all powerful air purifiers to compare with this AllerAir 4000. The test was conducted in a room of 400 square feet, and in 1 hour. I also brought exactly the air purifiers in the advertisement as testing samples, the Rabbit Air MinusA2 and Honeywell HPA600B. As you can see from the chart below, the AllerAir 4000 really matched the top-class efficiency, trapping 99.95% any pollutants down to 0.3 microns.
You should buy the True HEPA filter replacement after 2 years, and Activated Carbon filter after 2 – 5 years.

AllerAir 4000 Room Coverage
The AllerAir 4000 is high-end air purifier meant for larger rooms, and it can cover as much as 1500 square feet as suggested by manufacturer.
The ACH of AllerAir 4000 is 4X. It can deliver the air exchange every 15 minutes.
The CADR of AllerAir 4000 is 400 cfm in general. With quadruple the CADR rating of AllerAir AirMed 3, the AllerAir 4000 is truly for large rooms. However, the fan power is still below the trio of Dyson Pure Cool Link, Dyson Pure Hot+Cool and Dyson Pure Cool Tower, because the Dyson air purifiers are designed to be the cooling fan as well.

AllerAir 4000 Sound
AllerAir is not really good at handling the noise level, and it is quite reasonable for an air purifier with such high fan power. And because the air purifier’s performance is based on the fan power, we must accept the noise level as an inevitable fact.
The lowest noise level of this AllerAir 4000 is about 35 decibels (db), which is even better than the compact AirMed series. However, if you run it on highest speed, the noise level can reach 65 decibels, which even exceeds the noise level of some public places, and some people may find it hard to sleep on such noise.

AllerAir 4000 Power Consumption
In Breathe Quality, one of our most FAQs is “Do air purifiers use a lot of energy?”. In fact, an air purifier needs to run for a long time (usually more than 8 hours) to be efficient, and therefore, power consumption is an important criteria to decide which air purifier to buy.
We have a new fan power, so we can’t expect the power consumption to be as low as the previous AllerAir AirMed 3. For the lowest setting, AllerAir 4000 consumes as high as 55 watts. And I measured the rated power of this air purifier on highest speed to be 115 watts, which is a bit higher than normal.
If you run the AllerAir 4000 for 8 hours per day, you need to pay $20 to $41 annually.

AllerAir 4000 Additional Features
This section is similar in all air purifiers of AllerAir family. As the leading company in high-end air purifiers, the AllerAir said no to any kinds of fancy features, be it the Smart Sensor or anything else. The AllerAir 4000 is a traditional classic air purifier, without any additional features on it.
There won’t be even the filter replacement indicator or the Timer. There is only one manual knob to change the fan speed of this machine.
AllerAir 4000 Customer Service
As the leading air purifier company in the North America, AllerAir strongly focuses on the customer service. They ensure to give you not only the finest product in the world, but also the most comprehensive support policy as possible.
Their main selling point is the deepest carbon beds on the market, with up to 40 different proprietary carbon blends. To back up the high-quality air filters, they dare to give you difference back PLUS one air purifier for free, for any competitor’s unit with more relevant carbon + HEPA filtration at a lower price. So to say, AllerAir is really confident about their pricing policy.
Do you need help? AllerAir provides a toll free customer support phone-line (available Monday to Friday from 8 AM to 5 PM) and you can either call them at 888-852-8247, or live chat with them. If you contact them outside the business hours, you can email them via the Contact Us page.
Just like any air purifier brands located in the United States, AllerAir allows us to return the air purifier within 30 days, but you must take a 25% restocking charge. If you want to avoid the charge, be sure to return the products unused and unopened within 15 days. The filters can also be returned, but only in unopened condition, within 15 days.
AllerAir is one of the few brands that offers the 5-year warranty, for all air purifiers in the Pro 4 (formerly 4000), Pro 5 (formerly 5000) and Pro 6 (formerly 6000) series, as well as a 10-year warranty on parts (such as motor, cord, switch, wheels, etc). All air purifiers in the AirMed 1 and AirMed 3 only receive an 1-year warranty on both parts and labor.
It is clear that AllerAir wants to put more effort in their popular AllerAir 5000 than this old AllerAir 4000, especially when the AllerAir AirMed 3 has better air filtration system than this one. So to say, if you are in the buying process, you should choose the AllerAir 5000 instead.
