Oreck DualMax Air Purifier: Trusted Review & Specs

The Oreck DualMax is the ultimate Truman Cell air purifier, with a lot higher fan power, and absolute newer air filter. Today, we will make a complete Oreck DualMax Review, so you can check if it should be your next air purifier.

It seems the Oreck DualMax has been discontinued, as we can’t find the product in Oreck website for a long time. We recommend you to look for the Oreck Air Response Large instead. If you like the concept of permanent air filter, the Honeywell AirGenius 6 is also a good option.

Oreck DualMax ranks B- in our air purifier ranking list. We give the biggest and most thorough database of air purifier reviews in the world.

Founded in 1963, Oreck is a popular American air purifier brand in the world, with high influence just like the Dyson in United Kingdom. Oreck DualMax is the most powerful Truman Cell air purifier of this company, with mere power can compare with the HEPA lineup. Are you ready for the latest Oreck DualMax Review.

Oreck DualMax Price

Oreck got a lot right with their Oreck XL Professional, and though the next Oreck ProShield Plus doesn’t meet the expectation, we still have faith in the latest Oreck DualMax.

The Oreck DualMax is a real console air purifier, which tells you its real power to be double the predecessors. Glance over the spec sheet and you can tell the difference is clear, and I believe you will love the price tag of this Oreck DualMax. Yes, again, Oreck only charges you for $399 to buy the flagship Oreck DualMax in their official website. However, it seems Oreck has discontinued this Oreck DualMax.

But, to be honest, an air purifier with that fan power tries to join the competitive mid-range segment? It is far from any imagination. You can only find the AllerAir AirMed 3 to compare with such low fan power, otherwise the top dogs like Rabbit Air BioGS 2.0 and Levoit LV-H134 are a lot better performers than this today unit.

If you are looking for an air purifier with cooling fan power, I recommend you to select between the Dyson Pure Cool Link or Dyson Pure Cool Tower. It has the similar price as our Oreck DualMax, contains a True HEPA filter, and runs with a continuous high air flow.

Oreck DualMax Design and Size

The Oreck DualMax is huge, but in a very different way to other huge air purifiers like Austin Air HealthMate and AllerAir 5000. It’s imposing in both stature and design, over the old tower compact size from the previous models, and a heavy-weight body.

Starting with the dimensions, Oreck DualMax is a real console air purifier with 18.5 inches in height, and 12 inches in width. It only has one color option of Black, which is also the most premium color for a mid-range air purifier.

It also comes with a hefty weight of 16 lbs, and the Oreck DualMax is heavier than any other air purifiers with Truman Cell filter inside. Moving the air purifier is a bit difficult, especially when you can’t find any convenient handle to hold it.

Oreck DualMax runs a very strange air flow direction, from left-to-right. It is based on the back-to-front air flow system concept, and I must confess that I don’t see the reason to change to this Oreck direction. It is hard to place the air purifier properly to aim the fresh air output directly to the users.

Right on top, we will find a convenient small control panel. The Oreck DualMax, just like the Oreck ProShield Plus, can be managed with a remote control.

Oreck DualMax Filters

As the special air purifier from the Oreck family, we can’t normally count the quantity or check the air filter types in the Oreck DualMax. Now, let’s have a look for the 2-stage air cleaning system.

1. Pre-filter – The pre-filter screen is able to capture the large object of pollutants like large dust, pet hair or lint. It is attached with a Activated Carbon filter, to remove common household odors and chemical fumes. It has rinsable screen to be permanent.
2. Truman Cell filter – The patented filter of Oreck with Electrostatic Precipitator technology, which is one type of ionizer, to attract particles to the filter.

The latest patented Truman Cell air filter from Oreck DualMax eats a lot of space, and as a result, we only see a 2-stage air cleaning system as above. It still remains the principle of electrostatically charged the fine particles into the collector.

Just like the Oreck ProShield Plus, the Truman Cell air filter is combined with the patented Helios Shield, which is another source of ionizer (called Air Revitalizer in previous model), so it can reduce the odors from the air filtration process. The Helios Shield feature can be switched on/off.

Let’s move into the test of Oreck DualMax. As you can see from the chart below, the flagship Truman Cell air purifier had better performance than all previous models in a room of 100 square feet, with efficiency of 99.9% for trapping any particles down to 0.3 microns.

The Truman Cell air filter can last permanently, providing you maintain and clean it regularly. In fact, you can’t find any mid-range air purifiers with a permanent air filtration system like Oreck DualMax.

Oreck DualMax Room Coverage

Finally we will get a Truman Cell air purifier with much better room coverage. The Oreck DualMax is recommended for medium rooms, up to 200 square feet. It is still nowhere near the capability of other air purifiers in the same price range, like Oransi Max with 1100 square feet or Alen BreatheSmart 45i with 800 square feet.

The ACH of Oreck DualMax is 4X. This air purifier will exchange the air in your room every 15 minutes.

The CADR of Oreck DualMax is 161 Dust/ 135 Smoke/ 190 Pollen (cfm), which is a bit better than the predecessors.

Oreck DualMax Sound

Even for the higher fan power, Oreck DualMax still does a good job at keeping the noise level as low as possible. Running the device on lowest speed, I only measured the noise level of 23 decibels (db), which is just like the sound from rustling leaves.

Turn the air purifier into highest speed, you can notice the sound audibly. The noise level can reach 50 decibels, and it is quite like the noise level from other electric devices like air conditioner.

Oreck DualMax Power Consumption

One of our most FAQs is “Do air purifiers use a lot of energy?” because we need to run an air purifier for a constant long time, and power consumption is really a thing to consider.

Oreck DualMax, despite of its higher fan power than Oreck XL Professional, keeps the same power consumption of only 32 watts. It deserves to be the only Truman Cell air purifier with Energy Star rating.

If you run the Oreck DualMax for 8 hours per day, you will need to pay only $11 each year.

Oreck DualMax Additional Features

The Oreck DualMax can be managed via a remote control, just like the previous Oreck ProShield Plus. It is convenient to use, especially when the Oreck DualMax can’t be put tabletop.

Oreck DualMax comes with a built-in Night Light function as well as an amber light of indicator for cleaning filter. These are the most basic settings of Oreck air purifiers, which have been available since the first model.

Finally, you will have a Dry Mode in this Oreck DualMax, by pressing and holding the power button, to help remove any residual moisture in the Truman Cell air filter.

Our verdict

The Oreck DualMax is the console form of previous Oreck ProShield Plus, with much higher fan power and a newer Truman Cell air filter. It keeps the same price as the predecessors, so this could be the best air purifier with Truman Cell you can buy from Oreck.

It seems Oreck DualMax has been discontinued.
