They have three levels, the highest being a little noisy, so I tend to run them 24/7 on low or medium in most cases. The difference in air quality is very noticeable for me. I sometimes have the window open too, and although I don’t think this is ideal for air circulation, the effect of the purifier seems to exceed the impacts of open windows. It’s a powerful and very effective piece of kit. This time of year I’m usually taking antihistamines every day and still expecting to suffer a bit, but since getting these I don’t take meds every day and hardly have any issues with Hayfever or Asthma. They are very good in my experience.
Do you just leave them on 24/7, or just when you are in the house? Do you also leave windows open too, or does that defeat the purpose of them? We suffer with hayfever too, but need the windows open, especially in the evening to cool the house down in the height of summer. This morning neither of us have been outside and are suffering with hayfever symptoms already. Bloody annoying so just wondering whether this would help or not.
my filter arrived as a separate package entirely - worth contacting them.
Got mine too and happy, but no spare filter
Arrived yesterday and already felt the difference today, no hayfever symptoms at all while in my room with it (windows and doors shut). Compared to the rest of the week where I’ve had itchy eyes all day. Very good!
