## About
Filters are a running cost that is easy to ignore. Enter the filter price, how many your appliance uses, how often they need replacing and, if you like, the price of a compatible alternative. You get the yearly cost, the real cost per year of owning the appliance, and a schedule of replacement dates. It does not check compatibility: always match the exact model number against the manufacturer's or seller's compatibility list before buying a filter.

## How to use
1. Enter your values in the fields above.
2. The result updates automatically as you type.
3. Copy or note the figures you need.

## FAQ
**How do I know a filter fits my appliance?** Match your appliance's full model number to the filter's compatibility list on the maker's or seller's page. Similar looking filters often differ in size or seal.
