Hidden impurities and sediment buildup in our water sources can lead to a variety of household challenges. Issues like off-color or bad-tasting water, unpleasant odors from faucets, and stains on dishes are common concerns. These problems not only affect daily activities like cooking and bathing but also lead to quicker wear and tear on appliances. For families relying on this water for everyday use, these issues are more than inconveniences — they pose significant health risks.

Fortunately, inline filters for water are a great solution for providing fresh, clean supply on demand. They connect directly to a liquid supply line and are typically installed under the sink. They can also be installed behind an appliance that requires filtration, such as an inline refrigerator filter.

In this quick guide, we’ll show you the simple steps of installing and maintaining these purifiers, ensuring clean and crisp water straight from your supply lines, safeguarding your health, and extending the life of your appliances.

Let’s dive in!

Changing inline water filter is crucial for maintaining liquid quality.

  • Locate your device: Identify the filter position, typically beneath the sink or behind the refrigerator.
  • Turn off your supply lines: This is to prevent leaks during replacement.
  • Release pressure: Open a faucet to release pressure in the system.
  • Remove the old filter: Disconnect the old device, usually by twisting or pulling it out, depending on the model.
  • Install new filter: Place the new purifier into the designated space, ensuring a secure fit.
  • Secure connections: Double-check and tighten all connections to prevent leaks.
  • Turn on the supply: Restore the supply and check for any initial leaks.

How often should you change an inline water filter?

It’s recommended to change your inline filter every 6 months or as specified by the manufacturer. The frequency could vary depending on usage and water condition. Regular replacements ensure continued effectiveness in removing impurities and maintaining water quality.

How do you clean an inline filter?

Start by turning off the supply line and releasing pressure from the inline water filtration system by opening a faucet. Next, carefully remove the filter from its housing, taking care not to cause any spills. Gently clean the device with a soft brush or rinse it under running water to remove accumulated sediment and debris.

For a deeper clean, soak the filter in a vinegar solution for 15-20 minutes or use a mild bleach solution to disinfect it, then thoroughly rinse the device again. Ensure all parts are completely dry before reattaching it to the line. Next, turn on the supply source and check for any leaks.

Inline water filter cartridges

Cartridges house the filtration media responsible for trapping impurities, ensuring only clean water flows through. There are various types:

  • Activated carbon filters for odor and taste removal
  • Sediment purifiers for particles, and more specialized options like
  • Reverse osmosis for comprehensive purification.

Inline water filter installation is easy – it involves a simple connection to the water supply line, typically positioned under the sink or behind appliances. They fit snugly into the designated space within the inline filter. Regular maintenance involves replacing the cartridge at recommended intervals, typically every 6 months, to ensure optimal performance.

Choosing inline filter replacements

When selecting an inline water filter replacement, it’s important to match the cartridge type with your specific filtration needs. Here’s a quick guide to help you make the right choice:

  • Identify Filtration Needs: Determine whether you need a sediment, activated carbon or a specialized filtration systemr like reverse osmosis based on your water quality concerns.
  • Check Compatibility: To ensure a good fit, make sure the replacement cartridge is compatible with your device model and size when considering how to replace inline water filter,
  • Consider Micron Rating: This is a measure of the size of the smallest particles that a cartridge can screen. The lower the micron rating, the smaller the particles that will be extracted. Common micron ratings are 100, 75, 50, 25, 10, 5, 1, and 0.5.
  • Consider Usage: If your household has higher liquid usage, opt for a filter with a higher capacity to ensure longevity between replacements.
  • Review Manufacturer Recommendations: Follow the manufacturer’s guidelines for cartridge replacement intervals, typically every 6 months.


Inline water filters are an effective, user-friendly solution for enhancing your home’s water quality — they tackle impurities, ensuring a supply of clean water.
