Pros and cons
Coway Canada
Pros
- Rated 985.42 m³/h, which puts it near the top of the brands compared on air delivery.
- Covers up to 395 m², so a single unit handles a large open space.
- HEPA and carbon filtration (hepa h13 and carbon) in the same machine.
Cons
- Starts at CAD 119, higher than most of the purifiers tracked here.
- Filter sets at CAD 59 to CAD 118 a year add running cost on top of the purchase.
- A single market reach (CA) means this pricing and range apply in Canada only.
Molekule
Pros
- A mobile app comes with the purifiers, and Molekule covers purifier and humidifier with Air Mini+, Air Pro, Glow as the reference models.
- The 6 month change interval matches the 6 month median across the field, so supply timing is predictable.
- Entry at $129 for the Glow sits right at the €127.49 category median, so the ticket price is unremarkable in a good way.
Cons
- Filter fees run $159.98 to $279.98 a year, and Molekule places 42 of 46 brands on yearly filter cost, so the running bill soon overtakes the $129 entry price.
- Support runs on chat and help centre only, so there is no phone line for setup or filter questions.
- Purifier coverage of 23.22 to 92.9 square meters stops short of the 153.29 square meter category median, so open plan rooms need extra units or a larger rival.

Coway Canada
Who it suits

Molekule
Who it suits
- Homes in US and CA that want purifier and humidifier models from the same maker, with Air Mini+, Air Pro, Glow as the range.

Questions about each
Coway Canada
What does the cheapest Coway Canada purifier cost?+
Purifiers start at CAD 119, which is the entry figure for the Airmega range. That is above the middle of the brands tracked on entry price, where Coway Canada ranks 33 of 76. Buyers wanting the largest machine pay more for the extra capacity.
How much do replacement filters cost each year?+
Filter sets cost CAD 59 to CAD 118 a year, with changes falling due every 6 to 12 months. On this measure Coway Canada ranks 9 of 46 among the brands compared, so the running cost sits mid field rather than at either extreme. Budget for it in the same year as the purchase.
Molekule
How much does a Molekule air purifier cost to start with?+
The listed entry price is $129 for the Glow, and the reference models are Air Mini+, Air Pro, Glow. The larger purifier models sit above that ticket, and running cost is separate: filters are sold by subscription, so budget the machine and the supply as two lines.
What do Molekule filters cost each year?+
Filter fees run $159.98 to $279.98 a year, and Molekule ranks 42 of 46 brands on that line, which places it near the end of the tracked table. The change interval is 6 months, so plan supply payments around that cadence.
