Air purifier or ioniser?

I just keep our windows open.

I've only ever had ionizers but the thing with them is they cause all particulates in the air to drop to the floor. You will notice that when you move a piece of furniture or something on your bedside table. Therefore, they also drop on you. Are you OK with that? If the air purifiers have a filter which catches all the particulates, I would say go for one of those.

I live on a drafty narrow boat. Can't say I have thought about the purity of the air. I breath the air that is given to me by my surroundings.

My bedroom window is open 365 days a year (yes, including throughout the winter).

I do have ionisers in my kitchen and the lounge.

Can’t comment on either but have you tired an eye shield? I have a very good one from Mountain Warehouse- very inexpensive too!

I am pleased this thread has been resurrected. I had put the idea of getting one of these gadgets on hold. Thanks for the additional replies.

I can't open the windows because I am a light sleeper, the bedroom is in the front and I get woken by people chatting on their way to school/work and by any traffic going by.

I am also asthmatic and notice changes in air quality if fumes blow in from cars parking outside.

I don't fancy cleaning up black walls or table tops by using an ioniser so an air purifier seems the way to go provided that they are not noisy when left on all night..

Another Blueair fan here. If you do a little research it comes out top in many surveys. I will always open a window but sometimes its not possible. (noisy neighbours in hot tub until the early hours) Together with a Meaco quiet fan, it gives us a comfortable nights sleep and I wake without a headache. Normally if the window is closed I always seem to get a thick head! It will also be good when visitors are allowed again as it helps to remove airborn virus particles. Ive had mine almost a year now and the filter doesn't need replacing yet. I wish I'd had one when I lived on a busy main road as that is another reason to keep the bedroom window closed!

I suffer from allergies and get sinus pain. I use a Salin salt machine in my bedroom at night and it does help at times, but I find the noise can disturb my sleep. I live in a bungalow so can't leave my windows open, really miss being able to do that when it's really hot or my night sweats are bad.

I have to say, our BlueAir is a purifier - not an ionizer.
And Notright it isn't "artificial air" (whatever that is). It's ordinary air without petrochemical residues, bacteria, viruses and pollen etc.

Many years ago, I put an ionizer in my bedroom, having seen an ad claiming that it would remove harmful stuff from the air and not having been diligent in investigating the claim. A couple of weeks later, I got glandular fever and was ill for weeks. I then realised that large parts of the white surface on which is was placed had turned black. It seemed as if it was clearing out the air in the rest of the room by attracting stuff to itself. Unfortunately, it was on my bedside table, so I was maybe breathing in a concentrated dose of the bad stuff every night. I can’t prove that the ionizer caused the illness – it could have been coincidence – but I threw it away and I would never get another one.

Ours is also BlueAir.
We sleep with the window open both summer and winter but this is still fantastic for my husband and really has improved his sleep.

As Ginger says they are NOT all equal. I like that ours is a genuine HEPA filter and quite powerful. It can clean the air quickly. We run it for a short while before we go to bed and then on low through the night.

It's about the size of an old PC and costs very little to run. You do need to change the filters (according to use). These aren't cheap but we find it worth it.

Open windows for me.

Yes we had one in the bedroom a few years ago, it made the cream walls very dirty around the bedside table. DH got rid because you had to scrub the wall clean before you could repaint it.

I am not sure of the difference Ramblingrose22 but I am pricing up air conditioning units, to have one in my bedroom starting for the warmer weather this summer.

I can’t have any windows open at night due to living on the ground floor.

Good luck with your search.

My mother had an air purifier, which she was certain helped her various allergies.

I could never myself sense any difference in the room when the purifier was on, nor did being in that room help my allergies, but she was convinced it helped her.

I wonder if her conviction had something to do with the benefit she felt, and my lack of conviction affected the benefit I felt I received?

The best practical contribution to healthy air indoors is making sure that the humidity is somewhere between 35% and 50%. This is optimum for your mucous membranes to work properly. The glycan molecules on immune cells in your nose and airways work best within these limits. This is why we have more respiratory infections in the winter months when the air temperature means that humidity is low. You can get very inexpensive hygrometers on the internet. If the humidity is low, you can increase it with bowls of water and adding plants. If it is high, ventilate the area and remove any washing etc. I don't know why you want an ioniser. Water molecules themselves are ionised.

If you live near a main road, you just get lungs full of traffic fumes if you leave a bedroom window open, so maybe an air purifier would be a good idea.

I have a ground floor flat and dare not leave a window open at night in case a burglar gets in. So maybe I need some sort of air purifier.

We have Levoit air purifiers in the kitchen and bedroom. I did research before we bought them and they seemed the best all round. I think they do make the air feel cleaner and fresher, especially if you can't or don't open windows much. You can see how much muck they filter out when you change the filters - they are black. These are not the same as ionisers, which I don't go for. They just purify the air, reduce pollution and odours. You can have them on different settings. We leave them on 24/7. They make little noise on a low setting and you get used to it, it's not annoying. In fact, I think the low background "white noise" helps me to sleep.

I used to have an ioniser, but it got lost in a move. I found putting some paper underneath it mitigated the mess it caused (as @geekess says, the particles tend to end up around it).

I've not had an air purifier, but imagine they'd be OK as long as you don't have it pointing at the bed (a fan pointing at the bed overnight can cause sleep and health problems).

I got one many years ago when moved into a new airconditioned office. I cant say I found much effect. But it created a layer of gunk around it so be careful where you locate it, somewhere easy clear. It is supposed to negatively charge the air and this compensates for all the positive ions generated by electric gadgetds etc. It is what happens when water breaks like in waterfall or waves on shore. I have asthma and thought anything to clear dust a good idea.

Why introduce 'artificial' air. Nothing replaces fresh air. Even if the window is open just a little that's enough. Why do you keep the windows closed.?
