Air purifier or ioniser?

Has anyone tried an air purifier or ioniser?

I would like to get one for the bedroom as I normally close the windows at night and am wondering if the air quality would improve and if we would sleep better with one of these.

Any recommendations (or the opposite) would be appreciated.

I haven't tried either of those....bedroom window is always too the window of the bedroom opposite so there is always air passing through, plus I have a ceiling fan which circulates the air .

Thanks, crazyH.

I cannot have the door open as that would let light into the bedroom from the landing and I have to sleep in complete darkness.

Hope others will be able to tell me if they have tried either of these gadgets.

Yes I’ve got a couple of them bought from amazon, one in bedroom, one in kitchen

I have an air purifier which I have on in the bedroom in the daytime. Research them as they’re not all the same. Mine is blue air. I wouldn’t be without it.

Should say that you can use it at night and on a low setting it’s almost silent.

Ionisers are brilliant for removing tiny particles from the air in a room. They are cheap-ish, almost silent and very effective.

The downside is that you need to clean surfaces around the ioniser because that’s where a lot of the particles end up.

gingergirl, I have blu air, one in the bedroom and one in the lving room. Meaco airvax is a cheaper option. Blueair is better.

I wouldn't recommend and ionizer based on my own experience.

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.?

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.

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).

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 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.

Alison333 Tue 11-May-21 11:24:22

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.

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.

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?

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.

I don't know the OP's situation, but we cannot keep our windows open at night because we have no front garden . Our house faces directly onto a walkway. There are very few passers-by but if anyone has a conversation or is talking on their phone we can hear every word. It probably wouldn't wake me unless it was the teenager neighbour having a party, but it would certainly wake himself who is a poor sleeper at the best of times...

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.

Aepgirl Tue 11-May-21 11:49:42

Open windows for me.

NotSpaghetti Tue 11-May-21 12:43:44

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.

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.

NotSpaghetti Tue 11-May-21 12:54:15

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.
