Quick checklist
- 1. Measure the room first.
- 2. Price replacement filters before buying.
- 3. Check sleep-mode noise.
- 4. Estimate annual running cost.
Look beyond the sticker price
Running costs, consumables, subscriptions, delivery, installation and return terms can change the real cost. Compare options using the same ownership period and use case.
Before you buy
Define the must-have features first, then compare at least two or three options on the same criteria.
Final prices, stock, warranties and terms should be checked with the seller or service provider at the time of purchase.
