How we chose
How we chose
We compared filtration stages, True HEPA rating, room coverage, noise and current price across the family. Every model here lists 99.99% True HEPA filtration, so the differences came down to how many stages each one runs, how much floor space it covers, how loud it is, and what it costs.
The 5510 and 5520 are identical on paper: 4-Stage filtration, 392 sq ft of coverage, 5 fan speeds, 13.3 lb, and both at $199.99. The C545 and C610 both run 4-Stage filtration at $129.99, with the C545 covering 360 sq ft at 27 dB and the C610 listed at 4.8 sq ft of coverage and 22 dB. The C535 is the only 3-Stage unit, covering 370 sq ft at 27 dB for $109.99. The C909 covers the most at 522 sq ft, runs 4-Stage filtration, and is listed at 26.2 dB for $274.99.
On price, the C535 is the lowest at $109.99. The C545 and C610 cost the same, $20.00 more than the C535. The 5510 and 5520 cost $70.00 more than the C545 and $90.00 more than the C535, and the C909 costs $75.00 more than either the 5510 or the 5520.
Who should skip these
If you need coverage beyond 522 sq ft, skip this lineup. The largest room coverage here is the C909 at 522 sq ft. The 5510 and 5520 each cover 392 sq ft, the C535 covers 370 sq ft, and the C545 covers 360 sq ft.
If you want a filtration setup other than True HEPA with a carbon stage, these are not the right fit. Every purifier listed uses 99.99% True HEPA filtration. The C535 uses a 3-Stage setup; the 5510, 5520, C545, C610, and C909 each use a 4-Stage setup.
Price is another reason to look elsewhere. The C909 is $274.99, which is $145.00 more than the C545 and $145.00 more than the C610. The 5510 and 5520 are $199.99 each, $70.00 more than the C545 and $70.00 more than the C610. If you are weighing these against each other, the C545 and C610 cost the same at $129.99, and the C535 is the lowest price here at $109.99.
How to choose the right one
Start with coverage. The C909 covers 522 sq ft, the largest here. The 5510 and 5520 each cover 392 sq ft, the C535 covers 370 sq ft, and the C545 covers 360 sq ft. If smoke odour is the concern, choose a 4-stage filtration model: the 5510, 5520, C545, C610 and C909 are 4-stage, while the C535 is 3-stage.
Then weigh noise and weight against price. The C610 is rated 22 dB and weighs 8.3 lb; the C909 is 26.2 dB at 17.2 lb; the C535 and C545 are each 27 dB, at 14.7 lb and 11 lb. The C545 and C610 both cost $129.99, the C535 costs $109.99, the 5510 and 5520 cost $199.99 each, and the C909 costs $274.99. The C545 costs $20.00 more than the C535, and the C909 costs $145.00 more than the C545.
