When buying emergency water filters, there are several important things to consider:

1. Filtration capacity: Look for filters that can effectively remove bacteria, protozoa, and other contaminants, and that have a high filtration capacity.
2. Portability: Consider the weight and size of the filter, especially if you may need to carry it with you or move it frequently.
3. Durability: Choose filters that are designed to withstand heavy use and that are made from durable materials.
4. Ease of use: Look for filters that are easy to use, with simple instructions and minimal maintenance requirements.
5. Compatibility: Make sure that the filter is compatible with the water sources you are likely to encounter in an emergency situation.

As for how many filters you should have on hand, it depends on several factors, including the number of people in your household or group, the duration of the emergency, and the availability of other sources of water. A good rule of thumb is to have at least one filter per person, and to have a backup filter in case of damage or failure. It's also a good idea to have additional filters on hand if you anticipate needing to filter water for cooking or cleaning as well as drinking.
