NUOLUX Natural Air Purifying Bamboo Charcoal Bag Air Freshener 4packs*100g (Random Color)

These bags are excellent with a very strong absorption power. They work best in small spaces, keeping moisture out. When placed in kitchen cupboards, tea and stored dried goods stay dry and fresh - a noticeable difference. I've even tried putting one in the fridge the way you do with a box of baking soda, and fresh fruit and vegetables stayed fresh weeks beyond the normal lifespan. I once left one on my bed by accident and it somehow sucked out the odours from the divan base, up through the mattress. The only down side is you can't recharge them like with other brands so they are single use only - a waste of materials especially the pretty buttoned canvas bag. Would be great to be able to buy the charcoal inserts only and reuse the canvas bags to generate less waste.

Bought these to try and eliminate litter tray odours in my en suite bathroom (not an ideal location I know...) but can't really say that I've noticed much, if any, difference at all. I have 2 in the bathroom itself and 2 placed just outside the door.There weren't any instructions so not sure if they need to be 'charged' or 'activated'. Was keen to avoid using chemical air fresheners (for the sake of sensitive feline noses) but might have to resort to that after all.

I have used two of those bags in my son's cupboard in which an old very smelly backpack used to be stored. There was a strong disagreeable odour I couldn't get rid of. It took a couple of week (in fact I thought at first it didn't work) but now the odour is all gone. Great result.

I purchased these mostly because of the external reusable bags and because of the number of items which will make for ideal candidates to buy refills eventually.The bags are of decent quality and are not an eye sore if left hanging on a door handle in a closet and at 100gr its ideal for smaller places. Short of eradicating humidity and mould in Britain this will have to do to mitigate smells.If they work as desired, then I will be purchasing more of these.

I have used these in two small rooms and also two wardrobes. These air purifyers seem to keep the rooms and wardrobes fresher. I would purchase these items again.

Excellent product - early days as yet - put one in car and have one in bedroom - have read about benefits for a while now so am happy to try a air freshener that costs very little and doesn't give me a sore throat.

Hung these in a few different places, including a shoe cupboard, wardrobes, and near a cat litter tray. The wardrobes seem okay now, but I haven't noticed any difference whatsoever with the other places I've put them.

I like the look of these, they are attractive and not obtrusive. We use them to dispel the smell of mildew in my son's bedroom. So far so good.
