Replacing air purifier filters is a crucial task to maintain the effectiveness of your device. Most filters need to be replaced every 3 to 6 months, depending on usage.
The type of filter you have will determine how often it needs to be replaced. For example, HEPA filters typically last longer than activated carbon filters.
Air purifier filters can be replaced at home, but it's essential to follow the manufacturer's instructions to avoid damaging the device.
Filter Replacement Basics
Filter replacement is an essential part of maintaining your air purifier's performance.
You should replace your air purifier's filter every 3 to 12 months, depending on the type of filter and your air purifier's model. For example, Honeywell Pre-Filters should be replaced once every 3 months, while Honeywell HEPA Filters should be replaced once a year.
Some air purifiers have permanent filters that don't need to be replaced, but should be washed every 3 months. The filters in the OV200 air purifier, for example, should be replaced every 6-9 months of use.

How to Resize a Filter
Cutting a pre-filter to make it fit is a relatively simple process. Simply remove the pre-filter from its box and use the provided cutting template.
Following the cutting template will ensure your pre-filter is the correct size for its intended unit.

Differences Between Two Instances

In some air purifiers, you'll find two filters working together to keep the air clean. The pre-filter is designed to capture larger airborne particles like pet hair and dust.
The primary filter, often a HEPA, HEPA-type, or ifD filter, is the real workhorse that captures smaller microscopic airborne particles. It's the one that does the heavy lifting when it comes to removing allergens and pollutants from the air.
The pre-filter can also help reduce odors and VOCs, making the air feel fresher and cleaner. This is especially important in homes with pets or where strong chemicals are used.
These two filters work in tandem to provide a more comprehensive cleaning of the air. By capturing both large and small particles, they help create a healthier environment for you and your family.
