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.
Coolblue Belgium
Pros
- The camera listing covers recording to microSD card, a base station or a hard drive without a subscription, plus app live view and motion alerts, and local storage is offered.
- Support runs on email, chat and phone, and a spare parts shop keeps brushes, filters and mop pads orderable after purchase.
- Floor care spans robot vacuum, stick and handheld, so a robot vacuum can be bought alongside a stick or handheld vacuum in the same order.
Cons
- Floor care stops at robot vacuum, stick and handheld, so a buyer who wants an upright or wet-dry vacuum has to shop elsewhere.
- The app carries no energy reporting, so household energy use has to be measured elsewhere.
- A hub is required before bridges speak zigbee and wi fi, so smart home buyers pay for extra hardware before the first device goes in.
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.
Coolblue Belgium
Who it suits
- Belgian households replacing a vacuum or a purifier who want delivery, returns and support handled by one local operation.
- Camera buyers who want recording to microSD card, a base station or a hard drive without a subscription.
- Shoppers whose floor care shortlist is robot vacuum, stick or handheld, the types this range covers.
Who should look elsewhere
- Buyers who want upright or wet-dry vacuums, since floor care here covers robot vacuum, stick and handheld only.
- Shoppers outside Belgium, since Coolblue Belgium delivers only to Belgian addresses.

Questions about each
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.
What do replacement filters cost and how often do they need changing?+
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.
Coolblue Belgium
What does the cheapest robot vacuum cost at Coolblue Belgium?+
The lowest robot vacuum price is €199, and the top of the range is €1,199. Reference models are named at each end of the list, so the gap between the two prices buys hardware rather than a subscription. Neither figure renews after the purchase.
Is the flagship robot vacuum worth more than the entry model?+
The step up from entry at €199 buys a self empty dock, Lidar mapping and a mop pad that lifts 10.5 mm, on a machine that pulls 42,000 Pa and stands 8.9 cm tall. Buyers who already know they want a dock and a mop lift should go straight to the flagship.
