The First Shower Filter Designed Specifically for Hair Extensions

Not all shower filters are created with hair in mind.

Most shower filters are designed for general water quality. The Beauvoir Shower Filter was developed specifically to help protect hair extensions, color-treated hair, and the investment you've made in your hair.

Our replacement cartridge features a proprietary 3-stage filtration system. While traditional shower filters typically focus on removing common water contaminants, Beauvoir incorporates a third filtration stage designed specifically to support healthier-looking hair and help preserve extension quality and color vibrancy.

Manufactured by one of the world's leading shower filtration facilities, the Beauvoir filter combines proven water filtration technology with hair-focused innovation.

Why Replace Your Filter?

Over time, filter media becomes saturated and less effective. Replacing your cartridge regularly helps maintain optimal filtration performance.

A fresh filter helps:

  • Protect hair extensions from harsh water contaminants
  • Preserve extension color and tone
  • Help maintain color-treated hair
  • Reduce dryness and dullness caused by water quality
  • Support softer, smoother, more manageable hair
  • Extend the life and appearance of premium hair extensions

Beauvoir's Exclusive 3-Stage Filtration System

Stage 1: Sediment Filtration
Helps capture larger particles and impurities commonly found in household water.

Stage 2: Water Purification Media
Helps reduce chlorine and other contaminants that can affect hair quality and color longevity.

Stage 3: Hair Protection Layer
A Beauvoir-exclusive filtration stage developed specifically to help support hair extension integrity, color retention, softness, and shine.

Recommended Replacement Schedule

Replace every 3–6 months, depending on water quality and household usage.

Protect Your Investment

Hair extensions can cost hundreds—or even thousands—of dollars. Replacing your filter cartridge regularly is one of the simplest ways to help protect your extensions, preserve your color, and keep your hair looking its best every day.

Shipping

Each Beauvoir order is prepared with precision and care, ensuring that every detail arrives in perfect form. Complimentary standard shipping (3–5 business days) within the US is included on all orders over $300. Below that, standard shipping is a flat $13.99.

For those who prefer a swifter delivery, expedited shipping options are available at checkout for an additional charge.

Care, Performance & Limitations

Beauvoir extensions are a professional product and must be installed by a licensed stylist. Performance and longevity depend on proper installation, maintenance routines, and the use of compatible, extension-safe haircare products. Normal wear, changes in texture, and variations in tone can occur over time. Improper care, harsh products, excessive heat, or incorrect installation can contribute to dryness, tangling, or reduced longevity. By purchasing Beauvoir hair, you agree to follow our care instructions and to review them with your client.

Hi, I just wanted to reach out. I just received my first order from you guys and I was blown away with the quality of the packaging and the freebie I received. I do a lot of keratin bound extensions and was working with [another brand] for quite some time and saw their product diminishing, so it's refreshing to see a company pack their products so nicely and professionally! Looking forward to working with you on all my orders!
