#######

Honeywell is up against some tough competition. Philips has early mover advantage, models in all price brackets and a tonne of great reviews on its products. Mi, the Chinese company better known for its Xiaomi smartphones, has also released an air purifier that the editorial team here found hard to fault. gas dryer vs electric dryer Read about it in our Mi Air Purifier 2 review.

When the fan in the unit is running at full speed, the A5 generates upto 60 decibels of noise, which makes it one of the noisiest air purifiers that we’ve reviewed so far. Most brands try to keep their air purifiers under 55 decibels because they are used in the bedroom and having a noisy fan isn’t conducive to sleep! On lower fan speeds, the unit is still producing 46 decibels of noise. To give you some context around these numbers, the A5’s quietest noise is louder than some more expensive air purifiers (like the Philips AC4372) loudest noise.

The Honeywell A5 Air Purifier is in the basic category of what you want an air purifier to do: clean the air. Everything else is bells and whistles. In this respect, the only control you have over the air purifier is the fan speed which comes in three settings. electricity quotes by benjamin franklin As discussed earlier, even on the lowest fan speed, the unit makes an audible noise – a far cry from the whisper quiet operation of some air purifiers.

The coverage of the A5 is 323 square foot and at full speed the unit can clean an area of this size in 15 minutes. gas you up This gives it a Clean Air Delivery Rate (CADR) of 250 m 3/hr. The coverage means it’s ideal for small rooms, but we have some reservations about using in the bedroom due to the noise. If you can sleep with the ceiling fan on full speed, then you might not find any difference with the air purifier noise.

The real on-going costs come from the replacement filters that you have to buy. HEPA filters trap the smallest of particles but after three to four months their efficiency reduces as they become saturated with those particles. electricity prices by state Unfortunately you can’t just wash these filters like you would an A/C filter, they have to be thrown away and replaced.
