Replacement filters and accessories for vacuum cleaners and air purifiers: how to choose the right ones

A clogged filter, worn brush or missing mop pad can noticeably affect how well an appliance works. Even so, it’s not a good idea to order just any replacement filter or accessory kit. A product that looks the same won’t necessarily fit your Xiaomi, Dreame, Tapo, Eureka, Jafanda, Homintell, TRULIVA or MOVA appliance.

As a Joybuy Product Recommendation Officer, I focus on three things: compatibility, filter construction and maintenance. This helps you avoid buying the wrong product and keep a closer eye on ongoing costs.

Common pitfalls when choosing filters and accessories

1. Looking at the brand name alone

“Xiaomi filter” or “Dreame accessories” doesn’t tell you enough. A brand often has several models with different dimensions, fittings and filter shapes. For example, a filter for the Xiaomi Smart Air Purifier 4 Lite won’t necessarily fit the Xiaomi Smart Air Purifier 4 Pro.

Before you buy, check:

  • the appliance’s full model number;
  • the product name and compatibility list;
  • the filter’s shape and dimensions;
  • the number of items included in the pack.

2. Mistaking marketing claims for guaranteed performance

Terms such as H13 True HEPA filter, “removes allergens” or “fresh air” often describe a product feature or a claim made in the product information. According to information provided by the brands or retailers concerned, filters can help capture certain particles, odours or hairs. Your experience will also depend on factors such as how long the filter has been in use, how well it fits, the fan speed and the level of pollution in the room.

Look for specifications you can check, such as:

  • filter type: HEPA, H13 HEPA, activated carbon filter or pre-filter;
  • number of filtration layers;
  • dimensions and model compatibility;
  • whether it is washable;
  • recommended replacement interval.

3. Confusing washable and disposable filters

Not every vacuum cleaner filter can be rinsed. For example, the Xiaomi Smart Pet Care Air Purifier Filter states that it must not be washed or reused. According to the product information, the Tapo RVA102 accessory kit includes washable HEPA filters. Refitting a wet filter can cause damage or unpleasant odours.

Always follow the instructions for the specific product. Switch off the appliance and unplug it before replacing a part.

Important factors to consider

Filter type and layer construction

A HEPA filter is designed to remove fine particles from the airflow. For an H13 True HEPA filter, H13 refers to a classification within the EN 1822 filter classification system. This designation doesn’t mean that every product will fit every air purifier or automatically make a particular home environment healthier.

A combination of a pre-filter, HEPA layer and activated carbon filter serves different purposes:

  • a pre-filter traps larger dust particles and hairs;
  • a HEPA layer targets fine airborne particles;
  • activated carbon is used to reduce certain odours.

A pre-filter can be useful in homes with pets, as hairs and skin flakes tend to build up there more quickly and visibly. This doesn’t mean that every filter will remove all pet hair and allergens.

Compatibility and fit

A precise fit helps prevent gaps and makes installation easier. So check the model, not just the brand. For example:

  • TRULIVA KJ260 and KJ450 use different replacement filters;
  • Homintell Callisto is different from Homintell Kilo/Mercury;
  • Dreame H12Pro/H12Dual use different brushes from certain H14 or H15 models;
  • Tapo RVA102 is designed for the Tapo RV20 Mop and RV20 Mop Plus.

The model range is usually clearly stated for genuine parts. With compatible filters, it’s especially important to compare the product page with the label on your appliance.

Lifespan and maintenance

A recommended replacement interval isn’t a guarantee. How long a filter lasts depends on the number of hours it’s used, the amount of dust, whether you have pets and the air quality in your home. The product information gives the following guidelines, among others:

  • Xiaomi Smart Pet Care Air Purifier Filter: up to 12 months;
  • Xiaomi tap water filter: up to 3 months;
  • Homintell Callisto filter: replace after around 6 to 8 months;
  • Eureka J12 Ultra accessories: according to the product information, replace approximately every 3 to 4 months, depending on use.

Remember to check the cost of maintenance too. A kit with several filters, brushes, dust bags or mop pads can be more convenient if you carry out maintenance regularly.

Frequently asked questions

How do I know which vacuum cleaner filter I need?

Make a note of your appliance’s brand, model number and serial number. Then compare them with the compatibility information on the product page. Check the shape, dimensions and fitting too. For robot vacuums, you should also check whether you need a main brush, replacement brush, side brush, mop pads, dust bag or filter.

How often should I replace an air filter?

It varies by model and usage. The product information may, for example, recommend replacing a filter after three months, six to eight months or up to twelve months. Treat this as a guide and check the filter regularly. A visibly clogged, damaged or strongly smelling filter may need replacing sooner.

Can I wash a HEPA filter?

Only if the manufacturer or product information explicitly says that you can. Some Tapo filters are washable; the Xiaomi air purifier filters mentioned above are not. Allow a washable filter to air-dry completely before refitting it. Don’t use an air purifier or vacuum cleaner without the filter correctly in place if the manual says not to.
