Frequently Asked Questions

The area your room ioniser covers is bigger than the ground area of my house. Can I just use one in the hallway to cover all the rooms on one floor?

Unfortunately, no. Ions can’t travel through walls. (This is why we need ionisers in the first place.) And the amount that could pass through a doorway is too few to properly ionise the room beyond. So you really need one ioniser for each room you want to be covered.

How many ionisers do you recommend per household?

It is not absolutely necessary to install an ioniser in every room. We usually suggest that you start with one in the room you live in most (usually the lounge) and a second one in the bedroom for a relaxing sleep.

If I use my ioniser in a small room, will it generate too many ions?

No. Firstly, you can’t overdose on negative ions. And in any case, we recommend that the ionizer 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 enough ions for all situations.

Do they cost much to run?

No, Astrid ionisers are extremely efficient. They use less than a quarter of a watt of electricity. That works out around 6 months continuous use for just 1kWh (1 unit of electricity).

Are your ionisers noisy?

No, there are no moving parts to generate noise. The only sound is a very faint hiss from the needles where 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, our ionisers are designed for continuous use. And, as stated above, the running cost is negligible.

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.

Can your ionisers be described as negative ion generators?

Yes, although we have always simply called them ionisers, there are many other terms used by other people to describe them.
