I would too. Reserve the MP1's for emergency use.
One word of caution: FILTERS ARE NOT PURIFIERS. They will not remove viruses. When you purchase one, be sure to acetain which of the two it is.
If it is a FILTER, you still need to use a purification tablet post filtration.
Process is: FILTER - TABLET- wait 20 mins - NEUTRALISING TABLET.
You can, if you wish, delay adding the neutralising tablet untill you wish to use the water. That has specific advantages in terms of safeguarding your water from contamination.
With a PURIFIER, you have no such worries. Just follow the manufactures instructions.
