How to Compare Water Purifier Rental vs Purchase Costs
Renting a water purifier means no upfront cost but continuous monthly payments. Buying requires a large initial investment but only ongoing filter replacement costs. The break-even point is when cumulative rental costs equal the total purchase cost โ after that point, owning becomes the cheaper option.
Formula: Total rental cost = monthly fee ร 12 ร years. Total purchase cost = purchase price + annual filter cost ร years. Break-even (years) = purchase price รท (annual rental fee โ annual filter cost). Keep in mind that rentals often include maintenance and support services that ownership does not.
