Even top-rated models need regular maintenance, mainly in the form of replacing the filter. Consider how often you are planning to use it, since the more you’re using it the more they will need maintenance.
Additionally, some models might feature filters that need cleaning too, while others feature filters that you should replace.
When it comes to price, not only do you have to think about the unit’s actual cost, but you also have to consider the price of running the unit. Between electricity and replacing the filter, air purifiers for homes, do come with constant costs.
Ensure that you determine the amount of money it will cost to run the unit. This is to make sure you select a purifier that will suit your budget.
