Water is the first thing in an emergency kit: [Public Safety Canada](https://www.canada.ca/en/services/policing/emergencies/preparedness/get-prepared/emergency-kits.html) says to plan on about four litres per person per day. A household filter is for everyday water, and the label tells you what it’s certified to remove. Below are the water filters Price Tracker Canada checks at Canadian stores (pitchers, faucet and under-sink filters, reverse osmosis), with the price now and the 30-day low.

## What to check on the box

- **A certification mark.** [Health Canada](https://www.canada.ca/en/health-canada/services/environmental-workplace-health/water-quality/questions-answers-drinking-water-treatment-devices.html) advises buying a device certified to the NSF/ANSI standard for what you want removed, by a certification body accredited by the Standards Council of Canada. NSF/ANSI 42 covers taste and odour, 53 health-related contaminants, and 58 reverse osmosis systems.
- **Certified for what?** Certification is per contaminant: the box or the certifier’s listing says which ones (chlorine taste, lead, cysts…). Pick the filter for what is in your water.
- **Most filters don’t make unsafe water safe.** Health Canada notes that filters certified to remove parasitic cysts (NSF/ANSI 53) won’t remove viruses or bacteria. In an emergency, or under a boil-water advisory, [Health Canada’s advice](https://www.canada.ca/en/health-canada/services/food-drinking-water-safe-emergency.html) is to boil water, or if you can’t, add about 2 drops of unscented 5.25% household bleach per litre and let it sit 30 minutes.
- **Cartridges are the running cost.** Health Canada stresses following the maker’s maintenance instructions; a filter past its rated life stops doing its job. Check the replacement cartridge price, and how many litres each one lasts, before you buy the housing.

## Questions

### Will a water filter make tap water safe during a boil-water advisory?

Not a typical household filter. Health Canada notes that even filters certified to remove parasitic cysts don’t remove viruses or bacteria. Its emergency advice is to boil water, or disinfect it with a little unscented household bleach if you can’t.

### Which certification should a household water filter have?

Health Canada advises a device certified to the NSF/ANSI standard for what you want removed (42 for taste and odour, 53 for health-related contaminants such as lead, 58 for reverse osmosis), by a body accredited by the Standards Council of Canada.
