Frequently Asked Questions
How often should I clean or replace filters between guests?
For washable filters in rentals, inspect after every 1–3 bookings depending on occupancy and guest behavior. Clean more frequently if there are pets, smokers, or construction nearby. Disposable filters can be swapped after every 1–4 stays; a common practical routine is to check filters at each turnover and keep spares so you can swap immediately if one looks loaded.
Are washable filters safe for guests with allergies?
Yes — high-quality washable filters with a MERV 11 rating capture many common allergens like pollen and dust. However, MERV 11 can reduce airflow more than lower-MERV options; confirm your HVAC can handle it. If allergens are a concern but you need quick turnovers, use a high-MERV washable plus at least one spare so you can rotate while the cleaned filter fully dries.
Will using a washable filter damage my HVAC or void the warranty?
Most reusable filters are safe if they fit properly and do not obstruct airflow. The main risks are poor fit (causing bypass/leakage) and installing a filter with excessive airflow resistance on systems not designed for it. Check your HVAC manufacturer's warranty and specs; when in doubt choose filters labeled to increase airflow or stick within recommended MERV ranges for your system.
