Good to Know

Everything about the filter, cartridges and your order.

The Filter

What does Oh Oasis filter out?

It's a 5 µm sediment filter. It catches rust, dirt, sediment and other small particles in shower water. It doesn't remove chlorine.

How small is it?

About 4 × 6.4 cm and 50 g. It fits in the palm of your hand and slips into any toiletry bag.

Can I use it at home as well as on trips?

Yes. Lots of customers keep one on their home shower and another in their travel bag. Our Home & Travel Duo is made for exactly that.

Where is it made?

In Korea.

Fit & Setup

Will it fit my shower?

It uses the international G1/2 thread, which fits most shower hoses. Some countries, such as Japan, and some hotels use other sizes or fixed shower heads, so check before you go.

How do I put it on?

Unscrew your shower head, screw Oh Oasis onto the hose, then put the head back on. No tools needed.

It's leaking. What should I do?

Take out the rubber ring, sit it back in place and reconnect. Still leaking? Email us and we'll help.

Will it lower my water pressure?

You might notice a small drop, especially if your pressure is already low. A big drop usually means the cartridge is full and ready to swap.

Cartridges

How often should I change the cartridge?

About every 30 days, or roughly 2,000 L at 60 L a day. Change it sooner if it turns brown quickly or the flow slows.

Mine turned brown or yellow. Is it faulty?

No. The colour is the rust and sediment it caught. It means it's doing its job.

How many should I pack for a trip?

One a week is a good guide. Where the water carries a lot of sediment, like parts of Southeast Asia, a cartridge can change colour in a day or two, so bring a Refill Pack.

Can I rinse and reuse one?

We don't recommend it. Rinsing won't clear what's trapped inside, so a fresh cartridge works best.
