The area your Astrid ioniser covers is bigger than the whole floor area of my house. Can I just use one in the hallway to cover all the rooms on the same floor?
Unfortunately, no. It doesn’t quite work that way.
Ions can’t travel through walls (which is why we need ionisers in the first place) and the amount that can pass through a doorway is too small to properly ionise the room beyond. So you really need one ioniser for each room you want the air to be ionised.
How many ionisers do you recommend per household?
It’s not really necessary to install an ioniser in every room. We suggest you start with the rooms you spend most time in – usually the lounge and also the bedroom (for a relaxing sleep). If you work from a home office or spend a lot of time at a computer you may want to consider one there too.
If I use my Astrid ioniser in a small room, will it generate too many ions?
The answer is definately: No – you can never have too many negative ions!
Firstly, you can’t overdose on negative ions (the more the better). And in any case, we recommend the ioniser is underworked and having spare capacity rather than just coping – Not because it will put any strain on it, but everything that happens in the room has an effect on the ion levels. Say you switch on the tv, have friends round or have a full scale party. All of these things use up negative ions. By having a powerful model it will supply plenty of ions for all situations.
Do Astrid Ionisers cost much to run?
No, Astrid ionisers are extremely efficient. They use under a quarter of a watt of electricity – (less than a small torch bulb).
Are Astrid ionisers noisy?
No, there are no moving parts to generate noise. The only sound is a very faint hiss from the needles as they ionise the air. And you have to listen very carefully, really close beside the ioniser even to hear this.
Can I leave it on all the time?
Yes, Astrid ionisers are designed for continuous use. And most people do leave them on all the time (as stated above, the running cost is negligible). If you are away for any length of time, say on holiday, you may decide to disconnect it as you’re not there to feel the benefit. It’s up to you.
Will I need to buy replacement parts, such as filters or needles?
No, Astrid ionisers do not use filters, and are fitted with special needles designed to last the life of the unit.
I’ve heard that small ingestible ions are especially good for health. Do Astrid ionisers produce them?
Yes, the emitter needles generate small, mobile oxygen ions that are breathed in (ingested) and absorbed by the body.
Do Astrid ionisers need regular servicing or maintenance?
No special servicing is needed. Astrid ionisers are very reliable and will work for many years with virtually no maintenance – just a quick clean of the needles once every week or two. This is a very simple task with the supplied cleaning tool and takes less than 2 minutes.
Can your ionisers be described as negative ion generators?
Yes, although we have always simply called them ionisers, that is one of the many terms people use to describe them.
