OBMAO Spa In-Filter Mineral Sticks (4 Months) – Universal Hot Tub & Pool Filter, Yellow, 4 Pcs

Clearer water, simpler maintenance

OBMAO Spa in-filter mineral sticks are designed to live inside your hot tub filter cartridge. The four yellow sticks work continuously to help water feel softer and look clearer, while delivering minerals that support a balanced water profile for ongoing spa enjoyment.

How they work

• Efficient purification: The sticks work with the filter to subtly reduce visible impurities, helping water appear more transparent and inviting.
• Six types of natural mineral balls: Each stick contains six minerals that gently release trace elements into the water, helping you rely less on harsh chemicals.

• Long life, low maintenance: Load the sticks into your existing filter and let them run for up to four months without routine replacement.
• Easy installation: A complete user manual guides a quick setup so you can start enjoying clearer water sooner.
• Universal fit: Compatible with most hydrotherapy and hot tub filters, including massage tubs, recessed tubs, walk-in tubs, whirlpool tubs, and hot tub boats.

Real-world benefits

Imagine spa sessions with water that feels smoother to the touch and maintains a bright, clear appearance between drain-and-fill cycles. The mineral sticks are designed to be simple to use and to fit into many standard filter setups, offering a convenient option for pool and hot tub owners who value easy care and reliable results.

Note: This product is designed to improve the water experience by adding trace minerals and supporting a balanced water profile. It does not replace routine maintenance or water chemistry adjustments where needed.
