Types of Filters

Types Of Filters
When it comes to smart vacuums, filters are an essential component that helps to capture dirt, dust, and allergens. Choosing the right type of filter helps to ensure that your smart vacuum performs optimally, keeping your home clean and healthy. There are several different types of filters available for smart vacuums, such as HEPA filters, Activated Carbon Filters, Pre-Motor Filters, and Post-Motor Filters. Understanding the differences between them can be confusing, but it’s important to choose the right one for your needs. In the following sections, we will go into detail about each type of filter and what they are used for. For more information on replacing smart vacuum filters, see our guide.

HEPA Filters

HEPA filters are highly efficient filters designed to trap even the smallest airborne particles, such as dust, pollen, pet dander, and even some viruses. They are widely used in high-end air purifiers and smart vacuum cleaners to improve indoor air quality. HEPA filters are made of interlaced glass fibers that create a dense and effective filtering medium. Some vacuum cleaners feature an integrated HEPA filter, while others offer the option to buy and replace a HEPA filter.

There are different types of HEPA filters based on their efficiency and size. Here are the main types of HEPA filters available for smart vacuum cleaners:

  • True HEPA filters are the most efficient type of HEPA filters, capturing up to 99.97% of airborne particles that pass through the filter. They are typically used in medical and industrial settings, but also in high-end residential air purifiers and smart vacuums.
  • HEPA-like filters are less efficient than true HEPA filters, but still better than standard filters. They capture up to 95% of particles that pass through the filter, including some allergens and dust. They are cheaper than true HEPA filters and more widely available, but may not be as effective for people with severe allergies or respiratory issues.
  • Washable HEPA filters are designed to be washed and reused several times, reducing the need for frequent replacements. They are a cost-effective and eco-friendly option, but may lose efficiency over time and require careful cleaning to avoid damage.

Choosing the right HEPA filter will depend on your specific needs and preferences. Here are some factors to consider:

  • Filter efficiency: If you or someone in your household has severe allergies or respiratory issues, a true HEPA filter is the best option. Otherwise, a HEPA-like filter or a washable HEPA filter may be sufficient.
  • Filter replacement frequency: Depending on how frequently you use your smart vacuum cleaner, you may need to replace the HEPA filter every few months. Consider the cost and availability of replacement filters when choosing a HEPA filter type.
  • Vacuum cleaner compatibility: Make sure the HEPA filter you choose is compatible with your smart vacuum cleaner model and brand. Consult the user manual or manufacturer’s website for specific recommendations.

Activated Carbon Filters

Activated carbon filters are another type of filter that is commonly used in smart vacuum cleaners. These filters are designed to absorb and trap odors and other impurities, leaving the air in your home smelling fresh and clean.


  • Activated carbon filters are highly effective at removing odors and other impurities from the air, making them a great choice for pet owners or anyone with allergies or other respiratory issues.
  • These filters are also long-lasting, meaning that they don’t need to be replaced as often as other types of filters


  • Activated carbon filters are not as effective at removing fine particles like dust and pollen as HEPA filters, so they may not be the best choice for people with severe allergies or respiratory issues
  • Since activated carbon filters are designed to absorb impurities, they can become saturated over time and will need to be replaced eventually

When considering whether an activated carbon filter is right for your smart vacuum cleaner, it’s important to think about your specific needs and preferences. If you have pets or suffer from allergies, an activated carbon filter could be a great option for reducing odors and improving air quality in your home. However, if you are looking for a filter that will remove fine particles like dust and pollen, a HEPA filter may be a better choice.

Pre-Motor Filters

Pre-motor filters, as the name suggests, are filters that are located before the motor of the smart vacuum cleaner. These filters ensure that the motor is protected from dirt, debris, and dust particles. Without these filters, these particles could enter the motor and cause damage. Pre-motor filters usually come in the form of foam or felt pads or a combination of both.

The effectiveness of these filters is dependent on the material used and the surface area of the filter. A larger surface area of the filter increases the filtering capability. It is essential to consider the quality of material as well because certain materials may not capture all the microscopic particles. Pre-motor filters are often washable and reusable. Depending on the model, they can last for up to 3 to 6 months and may need changing sooner if they become too clogged.

One common error people make when dealing with pre-motor filters is leaving them until they become super clogged before cleaning or changing them. It is important to add checking your filters to your routine cleaning schedule. Some smart vacuums have a sensor that alerts you when the filter needs to be cleaned or replaced.

It is essential to follow the manufacturer’s instructions on how to clean or replace the pre-motor filter. Using water on filters that are designed to be disposable can result in damage or ineffective filtering. Before purchasing a smart vacuum cleaner, it’s good to research and understand the difference between washable and disposable pre-motor filters. We have written another article on this topic – “Understanding Washable Vs Disposable Filters on Smart Vacuums”.

Upgrade options for pre-motor filters are generally limited. The factory filter is more efficient and will fit perfectly into the vacuum. Some companies make a HEPA pre-motor filter that is an upgrade in terms of efficiency. If upgrading your pre-motor filter, ensure you note the type of filter required by your specific vacuum – this information is usually available in your user manual.

Pre-motor filters are an essential component of your smart vacuum. Protecting your motor is critical to the longevity of your smart vacuum. Ensure the correct filter is used for the model of the vacuum, check and clean or replace it regularly, and always consult the manufacturer’s instructions before cleaning or replacing it.

Post-Motor Filters

When it comes to smart vacuum cleaner filters, post-motor filters play an important role in keeping the air clean and free from allergens. These filters are placed after the motor and help to capture the fine dust particles that could otherwise escape through the exhaust.

There are typically two types of post-motor filters: foam filters and pleated filters. Foam filters are washable and can be reused for a longer duration, while pleated filters need to be replaced more frequently.

Here’s a table outlining the differences between foam and pleated post-motor filters:

Foam Filters Pleated Filters
Filter Material Synthetic foam Paper or synthetic fiber
Longevity Long-lasting, washable and reusable Need to be replaced more frequently (around once every six months)
Filter Efficiency Less efficient than pleated filters; captures larger particles but may not be effective on smaller ones Highly efficient in capturing fine dust and allergens down to 0.3 microns
Care & Maintenance Can be washed and reused multiple times Need to be replaced every six months to maintain filter efficiency
Cost More cost-effective in the long run due to reusable nature May be more expensive due to need for frequent replacement

When choosing a post-motor filter for your smart vacuum cleaner, it’s important to consider your individual needs and the environment you’ll be vacuuming in. It’s also crucial to keep in mind the efficiency and longevity of the specific filter to ensure it meets your requirements.
