Our Verdict

While it provides high end air cleaning performance, the Honeywell True HEPA Allergen Remover is held back by a relatively high price and a relatively noisy fan. The Coway AP-1512HH provides the same air cleaning performance with a much quieter fan and a lower price tag. If you can find the Honeywell on sale it is a great and capable machine, but at full price we would definitely suggest getting the Coway instead.

Our Analysis and Test Results

The Honeywell True HEPA Allergen Remover is a great air purifier, but has a somewhat noisy fan and operating costs that are slightly above average. If you're not too sensitive to noise it is a great machine, but better values can be found elsewhere.

Performance Comparison

The Honeywell True HEPA Allergen Remover was held off the top of our overall score leaderboard due to a loud fan and high operating costs.

In the sections below we detail how the Honeywell performed in all of our individual tests.

Air Cleaning Performance

The Honeywell Was one of the top performers in our air cleaning tests, sharing the top score of 8 out of 10 with three other models. Its CADR (clean air delivery rate) of 300 was one of the largest of the models we tested and makes it suitable for large rooms of up to 450 square feet. That power allowed it to remove 99.78% of the airborne particles in our testing room within half an hour. This was the fastest any model reached such a reduction. However, it didn't continue to lower the particulate count over the next half hour of testing, whereas some other models reached just slightly higher percentages by the end of the test. It was one of the best models in terms of odor reduction, but it still left quite a bit of a smoky stench behind in our testing room.


Noise is one of the Honeywell's downfalls. While we didn't find any of our purifiers to be unbearably noisy, the Honeywell was one of the worst, with a score of 4 out of 10. On high it makes a high pitched shriek that is very noticeable. If you're the kind of person that likes white noise it may fade into the background for you, but if you are sensitive to noises it may gnaw at you a bit. In comparison the Coway, its main competitor, makes more of a dull hum that some of us actually found relaxing. Turning the Honeywell down to medium and low knocks the volume down a peg, but the pitch remains the same and was still noticeable.

Ease of Use

The Honeywell earned a 7 out of 10 in our ease of use testing, putting it just behind the top scorers. It has simple, clear buttons on the top of the unit that allow you to easily select one fo four fan speeds, and set the off timer. The only downside is its size. At 17 pounds it is the heaviest model we tested, and thus the hardest to move around. It does have two recessed handles that make the task of moving it around a little easier, but most comparable models are at least 4 pounds lighter. Take the Coway, which has just as much power, but weighs in at only 12.7 pounds.

The Honeywell is fairly heavy  but its handles make it a bit more portable.

Operating Cost

The Honeywell was again one of the low scorers in our operating cost metric. Its estimated lifetime cost came out to a whopping $771. Only two models were more expensive. That high cost starts with the list price. It was also the most power hungry of the models we tested, gobbling up 0.065 kWh of electricity for each hour of operation. Assuming average electricity rates this works out to $34.16 every year. The filters are actually relatively cheap, lasting one year and costing just $60.

The Honeywell True HEPA Allergen Remover offers great air cleaning performance, and is priced accordingly. Its high list price and $771 estimated lifetime cost are both on the high end. In comparison, the Coway offers the same performance and its upfront and lifetime cost clock in at $240 and $556, respectively. For the vast majority of people this represents a better value.


The Honeywell True HEPA Allergen Remover is a great performer, but a relatively loud fan and high price make the Coway a better choice for most people seeking top notch performance.
