Let customers speak for us
from 1347 reviewsI love these laundry sheets. It’s super easy to use and the smell! My laundry room smells so nice just because the box with laundry sheets is there. The clothes after wash smell too, and actually smell days after. I would love to try other scents.

Easy to use, nice smell and clean toilet!

Removed a stain which was already there for some months, which was not removed with other washing soap.
Very easy to use and good smelling.

This spray really takes care of all the smells there can be in a household with 2 boys 😉.

I was finding that some of my washing (gym kit in particular) was coming out of the machine smelling 'cheesy.' I tried a variety of methods to eradicate this problem using all natural detergents as this is my preferred option. I deep cleaned the machine but was still getting the odour. I then saw an ad for Yokuu and it suggested that there was a build up of bacteria in the machine and that washing at lower temperatures was partly to blame. I felt I had nothing to lose, so purchased the sample pack. I am pleased to say that it has done the job and my gym kit smells lovely now!
I can also say that the toilet bomb works at treat too. Happy days!

I have had a dark spot in my toilet for ages. Tried a lot of other cleaning products but they never worked. It took only 2 toilet bombs to completely remove it.

The strips do what they’re suppose to do: wash and clean your laundry! Really good results and while using them, you’re also diminishing your ecological impact.

We like the subtle sent and they feel on our skin. And it's economical in use!

I love love love everything so far. Used the toilet bombs, they’ve helped with an old toilet I had already tried everything on. The surface cleaner works really on ALL surfaces, the glass cleaner is super and effortless, I love the hand and body wash. I didn’t yet use the floor cleaner, dishwasher tabs and washing machine sheets as I still had some old products to finish but I can’t wait to give them a go

Cleans well and does not leave residue on the dishes. Tried with dried tomato sauce left on a pan and was satisfied with result. Would recommend.

does the job really well, and lovely smell (not strong but fresh)

Ben jammer genoeg niet meer van de jongsten, heb meer dan een halve eeuw poetservaring … maar nog nooit zo‘n aangename, gemakkelijke, gezonde, uiterst doeltreffende, kortom geweldige producten meegemaakt als die van Yokuu. Wat een verademing hiermee te kunnen werken. Bij elk nieuw product alweer een topper erbij. Heerlijke zachte geur die luchtverfrisser!
Ik was een beetje bang voor de geurcombinatie, ik ben daar nl. niet zo zot van. Maar na het gebruiken van de spray was het een hele verademing. Eerst een subtiel parfum en daarna niets meer. En de nare geuren zijn ook verdwenen.
Het product heeft weinig geur, maar werkt tegen vieze luchtjes! De oude chemische luchtverfrissers zijn hier verleden tijd door dit product!
Huh?! Probiotics for cleaning?

Pssst... Here's the answers you're looking for

Hey, I'm Joris - the founder of YOKUU!
Whilst writing my bio-engineer thesis, I discovered that 99% of bacteria are healthy... So why are we so obsessed with killing them?
Here's a couple of our most frequently asked questions:
Collapsible content
+ What makes this product so unique? Does it mask or remove odours?
Most air fresheners just cover up smells with synthetic perfumes. YOKUU does it differently: our spray uses 1 billion probiotics to break down odour molecules at the source.
The patented nozzle releases ultrafine droplets – no gas, no chemicals – that stay in the air, settle on surfaces, and let good bacteria do the rest.
No heavy cloud. No headache. Just clean-feeling air.
+ Is it safe for kids and pets? Does it contain alcohol or gas?
Yes. Once the pearl is dissolved in water, the spray is completely safe for use around the home. No alcohol, no propellants, no chemical fumes. You don’t have to worry about inhalation or surface contact.
+ Does it contain perfume? What if I’m allergic to lavender or limonene?
Yes, but only natural. The scent is a subtle blend of lavender and rosemary, all from natural sources. No synthetic fragrances, no fixatives, no overpowering clouds - just a light freshness that supports good air quality.
Allergic reactions are only possible from direct contact with the dry pearl. Once dissolved, the scent is diluted by over 100x. At this low concentration - and with the product intended for use in the air, not on skin - the risk is negligible. Still worried? Feel free to reach out.
+ How do I use it?
It’s as easy as 1, 2, 3:
- Fill the reusable bottle with tap water
- Drop in the pearl and let it dissolve fully (around 30 minutes)
- Lightly spray into the air whenever you want to freshen up
One pearl makes 300 ml of air freshener that’ll last you for months.
+ How long does it stay good after dissolving?
Up to 12 months. Once dissolved, the spray stays stable and effective for a full year. So no pressure - just use it at your own pace.
+ Does it work in large spaces? Will it leave stains?
Yes. The mist spreads evenly through bigger rooms thanks to our fine-spray nozzle – perfect for living rooms, bedrooms or open kitchens.
The formula is clear, water-based, and stain-free – no oils or nasties.
+ What makes YOKUU different from classic air fresheners?
Strong smells, headaches, quick fade-outs, chemical vibes – that’s what most sprays leave behind.
YOKUU? A soft natural scent, good bacteria that clean the air, and no gunk for your lungs. You’ll feel the difference.
