Pros and cons
Alen Air Purifiers
Pros
- 637.125 m³/h of clean air delivery with 260.13 m² of stated coverage, so a single unit handles a big open room.
- Filters last 12 to 15 months and cost $79.20 to $99 a year, which spreads the running cost over fewer purchases.
- Runs at 25 dB on the quietest setting, so a machine in a bedroom does not need switching off at night.
Cons
- Entry price of $149 ranks 49 of 76 brands, so this is not the cheapest way into the category.
- The catalogue is limited to purifier, so Vornado Air or Daewoo Electricals suit a buyer who also wants a fan or a dehumidifier.
- Availability is listed for US alone, so a buyer elsewhere has less reason to choose this brand over Clarifion.
Water & Wellness
Pros
- Certified NSF Standards with independent testing across a wide contaminant set including lead, PFA and fluoride
- PFAS and lead reduction confirmed on the AquaTru range
- Installation is not required, so a countertop system sets up with no plumber
Cons
- Filter cost of $89.87 a year ranks 18 of 46, so the running cost sits above the middle of the field
- Entry price of $375 ranks 37 of 52, higher than most rivals at the starting rung
- Cartridge life of 2,271-litre ranks 15 of 26, below the group median
Who each suits
Alen Air Purifiers
Who it suits
- US buyers who want a single purifier sized for a large open room rather than a small bedroom.
- Households that want app control alongside phone and help centre support from the maker.
- Owners who plan to keep one unit running long term, since 12 to 15 months between filter changes spreads the cost of $79.20 to $99 a year over fewer purchases.
Who should look elsewhere
- Buyers who want fans and humidifiers as well as purifiers, since Vornado Air covers purifier, humidifier and fan.
- Homes that also need drying, since Daewoo Electricals covers purifier, dehumidifier and fan.
- Pet odour cases, since Clarifion lists a pet smell neutralizer among its models.
Water & Wellness
Who it suits
- US households that want certified contaminant removal including lead, PFA and fluoride
- Renters and busy families who cannot host a plumber, since installation is not required
- Owners who prefer buying filters outright, with cartridges at $29.95 to $59.95
Who should look elsewhere
- Buyers in other markets, since the range covers US only
- Shoppers chasing the cheapest running cost, because $89.87 a year ranks 18 of 46

Alen Air Purifiers
How much does the cheapest Alen purifier cost?+
The entry tower purifier sets the entry point at $149. Filters for the top BreatheSmart model add $79.20 to $99 a year on top, so the yearly figure matters as much as the sticker price for anyone keeping the unit for years.

Filters for the top BreatheSmart model run $79.20 to $99 a year, and filters hold for 12 to 15 months between changes. That interval sits above the 6 months typical across the category, which is why the yearly figure reads as reasonable.
Water & Wellness

What do replacement filters cost over a year?+
