Frequently Asked Questions (FAQs)

1. Are inline water filters worth it?

Yes, inline water filters are worth it. They offer several benefits, such as constant operation without the need for container emptying or activation. They are known for their durability and effectively remove sediment, chlorine, bacteria, and other impurities from the municipal water supply before it reaches your plumbing fixtures and appliances.

2. What is an inline filter for IV?

An inline filter for IV is a device that separates the whole unit into a patient side and an air-vent side using a membrane. Proper priming techniques ensure that the fluid fills the air-vent side first, saturating the membrane, and then fills the patient side. This helps ensure safe and clean administration of intravenous fluids.

3. What are the benefits of inline filters?

Inline water filters provide point-of-entry filtration, treating water as it enters your home. They remove sediment, chlorine, bacteria, and other impurities from the municipal water supply. By installing them on the main water line, they protect your plumbing fixtures and appliances, providing cleaner and safer water throughout your home.

4. What is a 0.22 micron filter used for?

A 0.22-micron filter is commonly used in patient care to remove bacteria. It is one of the smallest filters used in this context. However, it's important to note that there are currently no filters available that can effectively remove viruses. Some intravenous medications may require specific filter sizes or may not be administered through a filter at all.

5. How long do inline filters last?

The lifespan of inline filters depends on the specific system and the type of filters used. In a typical 5-stage model, the sediment filters (2 - 5-micron) in stage 1 are usually changed every 6 months, while the carbon filters (4 - 5-micron) in stages 2 and 3 are also changed every 6 months. It's important to follow the manufacturer's recommendations for filter replacement.

6. How often do you change inline filters?

The frequency of inline filter changes depends on the cleanliness of the fluids being filtered and the condition of the seals in the system. As a general lab practice, it is recommended to include filter replacement as part of the system's preventative maintenance routine. Typically, maintenance occurs every six months to one year, but it's important to assess and monitor the specific conditions of your system.
