The filtration technology used in the product can significantly impact the quality of your water. Common types include activated carbon filters, reverse osmosis systems, and ceramic filters. Research what contaminants you’d like to remove, and choose a filter accordingly.

Some filters require more complex installations than others. Ensure you choose a product that fits your DIY skill level unless you plan on hiring a plumber.
6. Brand Reputation
