Your Questions Answered

How will the Sima Shower Filter benefit my skin and hair?

The Sima Shower Filter removes impurities like chlorine, heavy metals, and harsh minerals from your water. These are the hidden culprits behind dryness, irritation, dandruff, and brittle hair.
By filtering them out, Sima helps keep your skin hydrated, soothed, and clearer, while leaving your hair softer, shinier, and more manageable.

Is it compatible with my shower?

Yes — the Sima Shower Filter is designed to fit most standard fixed, screw-on shower heads.
⚠️ Please note: it is not compatible with handheld showerheads connected by a hose, or with built-in/custom shower systems.

Does it affect water pressure?

Not at all. The Sima Shower Filter is engineered to maintain steady water pressure while trapping impurities. You get the same refreshing shower, but with water that’s gentler on your skin and hair.

Do I need to replace the filter?

Yes. Each filter lasts around 3 months, depending on water quality and usage.
For best results, replace the cartridge every 3 months to keep enjoying clean, effective filtration.

How easy is it to install?

Super easy — no special tools needed. The Sima Shower Filter comes with a universal wrench and clear instructions. You’ll have it set up in minutes.

Why should I subscribe?

Regular replacement ensures your filter keeps removing chlorine, heavy metals, and irritants. Over time, the filter media becomes saturated and less effective.
With a subscription, you’ll never miss a replacement — meaning consistently cleaner water, healthier skin, and stronger hair.
