UniBond AERO 360° Moisture Absorber Waterfall Freshness Refill Tab, Aromatherapy, Ultra-Absorbent and Odour-Neutralising, for AERO 360° Dehumidifier, Condensation Absorbers, Twin Pack (2 x 450g)

I Don't know how they work, but they really are effective. The actual units aren't bad looking either. I'm using the Waterfall refills at the moment and they have a nice 'n fresh scent that gets stronger the harder they work, but never gets overpowering. Dead easy to set up, the first drips of water in the collection tank start after about an hour. The tank's a good size and, by the time the refill's gone, the tank's about half full. The refills last for about 4-6 weeks in an average size spare bedroom that we use for clothes drying during the Winter, and there's very little condensation on the windows, even on a frosty night. There used to be lots before we started using these. The one in the Lounge lasts for 6-8 weeks. Bearing in mind how well they work, and the condensation and mildew etc they prevent I reckon they're excellent value for money, too.

These are great,got them on subscription, use in my sons bedroom

Works and draws moisture out.. never really noticed a scent. Only buy as bundle or when on offer due to price as depending where you put them can need replacing quite often.

Works well. Leaves a pleasant smell in cupboard

Very happy with my purchase good quality , great price & quick delivery Cheers
