Introduction

Water filtration is crucial for ensuring clean and safe drinking water, but not all systems use reverse osmosis (RO). While RO systems are popular, alternatives exist that can effectively filter water. This article evaluates the best water filters without RO based on specific parameters.

Parameters for Evaluation

The evaluation of water filters without reverse osmosis is based on the following criteria:

  1. Filtration Efficiency: The percentage removal of common contaminants such as lead, chlorine, and bacteria.
  2. Flow Rate: Measured in liters per minute (L/min), indicating how quickly water is filtered.
  3. Capacity: The total volume of water the filter can process before requiring replacement, given in liters.
  4. Maintenance: The ease and frequency of filter replacements or cleaning required.
  5. Cost: Both initial purchase cost and ongoing maintenance expenses.
