Which is Better: One Large Air Purifier or Two Smaller Air Purifiers?

We often get asked this question, as one of Smart Air’s Blast Mini air purifiers produces approximately the same amount of air as two Sqair air purifiers. The choice as to which is better: a single, bigger purifier with higher airflow, or two smaller purifiers evenly separated depends on where you’ll be using the purifier.

Here are some things to consider when choosing between one larger air purifier and two smaller air purifiers:

  1. Noise: If you are sensitive to noise, then often a single larger air purifier will have a lower noise level. You should check the specifications of the two air purifier models you are comparing.
  2. Air circulation: If your room has poor air circulation, or is a complex shape (such as an L shape or a long thin shape) then you may benefit from multiple smaller air purifiers to improve ventilation. Two air purifiers placed at different locations in your room may help improve air circulation.
  3. HEPA filter lifespan: Larger air purifiers may have larger HEPA filters, which have a longer lifespan. For example, the Blast Mini air purifier has a large HEPA filter that lasts 13 months, whereas the smaller Sqair air purifier has a HEPA filter lifespan of 6 months.
