Most people know they need to change the filters in their air purifier, but they may not know how often they should do it or when the filters should be replaced.
We’ll cover everything you need to know about air purifier filters in this post, including how often to replace them and what factors affect how long they last. We’ll also dispel some common myths about air purifier filters.
How long do air purifier filters last?
The life expectancy of an air purifier filter will depend on the specific filter and the type of air purifier.
Generally speaking, most air purifier filters should be replaced every 6 to 12 months. However, it’s important to check the specific filter’s instructions, as some filters may need to be replaced more often (e.g., every 3 months) or less often (e.g., every 18 months).
If you’re not sure when your filter was last replaced, or if you’re noticing that your air purifier isn’t working as well as it used to, then it’s a good idea to replace the filter sooner rather than later.
Why do air purifier filters need to be replaced?
Air purifier filters need to be replaced for two key reasons: to maintain optimal performance and to ensure your health.
Replacing your air purifier filters at the recommended frequency (usually every 6 months to 1 year, depending on your air purifier model) maximises the removal of airborne particles. Over time, dirty filters can’t work as effectively and may even release harmful particles back into the air.
It’s also important to replace your air purifier filters because they can become a breeding ground for bacteria and other allergens. A recent study found that 25% of dust mites found in air purifier filters were still alive and well after being removed from the filter. Yuck!
So, when should you replace your air purifier filters? It depends on your model, but usually every 6 months to 1 year is a good rule of thumb.
How often should you replace your air purifier filter?
The frequency at which you need to replace your air purifier filter will vary depending on the type of filter it uses. Some filters need to be replaced every few months, while others can last up to a year or more.
To find out when your filter needs to be replaced, check your air purifier’s owners manual or contact the manufacturer. They should be able to tell you how often the specific filter in your air purifier needs to be replaced and how to tell if it’s no longer effective.
What are the signs that you need to replace your air purifier filter?
There are a few key signs that will let you know it’s time to replace your air purifier filter. If your air purifier is leaving black streaks on your walls, that’s a sign the filter is clogged and needs to be replaced.
If the air purifier isn’t removing as much dust, pollen, or smoke as it used to, that’s another sign the filter might need to be replaced. And finally, if the air purifier is making more noise than usual, that could also be a sign the filter needs to be changed.
How to extend the life of your air purifier filter
It’s important to keep your air purifier filter in good condition if you want it to be effective at removing harmful pollutants from the air. Here are a few tips on how to extend the life of your filter:
- Regularly vacuum or sweep particles from the surface of the filter. This will help keep the filter clean and functioning properly.
- If you have pets, be sure to regularly clean the filter as pet hair can clog up the pores and reduce the effectiveness of the filter.
- Don’t forget to replace the filter when it’s time! Many air purifiers come with a timer or indicator light that will let you know when it’s time for a new one.
How to choose the right air purifier filter
It’s important to know how to choose the right air purifier filter because not all of them are created equal.
There are a few factors you need to take into account when selecting a filter: the type of air purifier, the size of the unit, and the type of filter.
Each type of air purifier will require a specific type of filter. So, it’s important that you research which filter is compatible with your air purifier before making a purchase.
The size of the unit is also important to consider when selecting a filter because not all filters are made to fit every air purifier. Make sure to measure the size of your unit and find a filter that matches.
Some filters are better at capturing allergens while others are better at capturing smoke and odours. So, it’s important to choose a filter that meets your specific needs.
Air purifier filters should be replaced every 6 to 12 months, depending on the type of filter and the amount of use the purifier gets. If the filter is not replaced when it’s needed, the air purifier will not work as well as it should, and may even stop working entirely. It’s important to replace the filter regularly in order to keep the air in your home as clean as possible.
