Dayton 2HPB1 Air Purifier: Trusted Review & Specs

Dayton has thrown all of its traditional features at a bigger air purifier – the flagship Dayton 2HPB1. It is the most complete air purifier of this company, but with its high price, it is quite irrelevance for most users. So, it’s time for the Dayton 2HPB1 Review.

  • Quite expensive

Dayton finished the series of personal air purifiers with a big, bulky and strong machine named Dayton 2HPB1. However, given the low stock and outdated features, this air purifier is just nowhere in the competition. So, today we want to introduce to you the Dayton 2HPB1 Review.

Other Dayton’s Air Purifier Reviews

Dayton 2HPB1 Price

If you love the old-school air purifier devices, certainly you shouldn’t miss the Dayton 2HPB1. It is the flagship of a series of portable air purifiers came with remote control. Let’s see whether you can forgive the so-so performance and its strangely high price or not. Otherwise it’ll be a long way down your list.

Enter the Dayton 2HPB1, and its brother – Dayton 2HPB2, a device that’s very recognizably Dayton air purifier device, with large air grill and traditional gray color. It is bigger and stronger, and it sets the price at least double the closest models: the Dayton 2HPC3 or Dayton 2HPB8.

It’s as unconventional as its twin brother, but it only offers a simple 4-stage air cleaning system. However, the device is fully certified by the California Air Resources Board (CARB) for electrical safety and ozone emission limit under 0.05 parts per million (ppm). And that’s why it is more expensive than its brother.

So to say, the official price tag of the Dayton 2HPB1 is $489 on Grainger website. You can follow our deal for this product, but I recommend you to look for other air purifier brands. The reason? Dayton 2HPB1 is too expensive to justify its price.

In the same price range, you will get a lot of better air purifiers. The Vornado PCO575DC, Oransi mod Jr and Oransi Max offer better specs, while being covered with a 10-year warranty. If you want an air purifier with the latest smart feature, you can also look for the Rabbit Air MinusA2, Molekule Air Mini or Dyson TP04.

Dayton 2HPB1 Design and Size

The Dayton 2HPB1 may not be the portable air purifier or tower air purifier like any previous Dayton devices, but it’s solid built for greater purpose. It comes with the most popular gray color option from this company, but it remains the same body material as the budget products. Overall, it gives the Dayton 2HPB1 a very cheap feeling, which doesn’t justify its high price.

Together with the Dayton 2HPB2, our today unit shares the same size, with the height of 24.75 inches, and the width of 16.5 inches. It is very big, and you should only use this air purifier in a large space.

Also, I think this is not the original design concept of Dayton, as it clearly borrowed from the Winix‘s old models. Certainly the Dayton 2HPB1 is uglier than new models of Winix, most notably the Winix 5300-2 and Winix 5500-2. You should look for the design of Winix C535 to see how far the South Korea air purifier has improved.

Dayton 2HPB1 runs a bottom-to-top air flow system concept, with large air grill for the air inlet. It is capable of holding a bigger fan motor, to clean the room much quicker than the predecessors.

The control panel is placed on front, and I’ve said many times that it’s very unconventional in any modern air purifiers. Therefore, the design of the Dayton 2HPB1 is a big minus to go for.

It’s heavy, clearly for its huge size, at 24.2 lbs. You should avoid moving this air purifier too often.

Dayton 2HPB1 Filters

The main difference between the Dayton 2HPB1 and the Dayton 2HPB2 is the filtration system, because the Dayton 2HPB1 only runs a 4-stage air cleaning system. However, it is the only Dayton flagship to be verified by the CARB, so it can be sold in California.

  1. Pre-filter – A layer of HEPA pre-filter to remove large and medium particles such as dust, pet hair, fur and lint.
  2. HEPA Carbon filter – A combination of both True HEPA filter and Activated Carbon filter, to trap 99.97% of any particles as small as 0.3 microns, like pollen, mold spores, pet dander, dust or dust mites. It can also adsorb odors and chemicals.
  3. Ionizer – Anions charge the pollutants back to the mechanical air filter. Can be switched on/off.

Dayton 2HPB1 showed a promising efficiency in a room of 200 square feet, as it trapped 99.93% of all airborne particles down to 0.3 microns. This result was better than the Oreck Air Response Turbo and Oreck AirInstinct 200, which are the current flagships of this U.S brand.

But I see many air purifiers with better performance, for example the Boneco P400, Alen BreatheSmart FIT50 or Austin Air Allergy Machine Jr. This is the mid-range segment, and such performance in a medium room of 200 square feet isn’t exceptional at all.

You will use the strongest HEPA filter of Dayton – model 2HPB5, costing $112. This filter can last for 12 months, and I recommend you to only use Dayton genuine filter replacement.

Dayton 2HPB1 Room Coverage

The Dayton 2HPB1 is recommended to run in a room from 645 to 861 square feet, which is clearly insufficient with its low fan power.

The ACH of Dayton 2HPB1 is 4X. The Dayton 2HPB1 can exchange the air in your room every 15 minutes.

The CADR of Dayton 2HPB1 is 197 cfm in general. I think you should only use this air purifier for any room up to 400 square feet.

Dayton 2HPB1 Sound

A strong air purifier requires a powerful fan motor, which is related to high noise level. You can’t expect an air purifier to run quietly while being efficient. However, a noise level of 68 decibels (db) is beyond imagination, and I believe you shouldn’t often use Dayton 2HPB1 on highest speed.

The Dayton 2HPB1 is more suitable for a large room with such noise level, but its fan power is a bit weak comparing to other air purifiers like Honeywell HPA8350 or Dyson Pure Cool Tower. Sadly, these air purifiers are cheaper, and they offer many cool additional features that you can’t have in this old Dayton air purifier.

Dayton 2HPB1 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.

Dayton 2HPB1 has a lower power consumption than its twin brother – the Dayton 2HPB2, because it doesn’t have the UV bulb. However, the power consumption is still high at 98 watts.

If you run the Dayton 2HPB1 for at least 8 hours per day, it would cost you $35 each year.

Dayton 2HPB1 Additional Features

Just like the Dayton 2HPB2, Dayton 2HPB1 proved its flagship status with the dedicated Smart Sensor. Using both odor and dust sensors, the Dayton 2HPB1 has a more in-depth and correct analysis in tracking fine airborne particles. Then, it will automatically adjust fan speed based on current air quality status.

It also introduces the Mute Mode, to keep the air purifier on lowest fan speed. You won’t notice any sound when running the air purifier in this mode.

Finally, we have a remote control, which is signature for any Dayton air purifier products. There is a basic Timer setting to use, which schedules the time off for this Dayton 2HPB1 after 2, 4 and 8 hours.

Dayton 2HPB1 Customer Service

The Dayton products are now distributed by the W. W. Grainger Inc only, so actually, you won’t get proper support if you buy from other vendors. You should contact Grainger at 800-472-4643, or live chat with them online to ask more questions.

So far, Grainger offers 1-year warranty for all products sold by them. If you get a Dayton air purifier from other source (for example our deal), you won’t be covered with this warranty.

Our verdict

Dayton 2HPB1 has been eagerly awaited by Dayton enthusiasts and it absolutely hits the mark for that audience, but I just wonder if there are any kinds of enthusiast? Or else, the Dayton 2HPB1 misses many important parts to compete in a more cautious mid-range segment. Perhaps, we can say goodbye to any Dayton air purifier products, and look for much better alternatives.
