What is the HEPA Filter?

A HEPA (High-Efficiency Particulate Air) filter is an essential component of the RAINBOW vacuum cleaner, serving as the final stage of filtration before the machine’s air outlet. This washable and reusable filter is designed to provide high efficiency in capturing particles. 

The HEPA filter is highly effective in capturing particles with a size of 0.3 microns or greater, ensuring a filtration efficiency of 99.997% (by weight). It serves as a supplementary filtration system to the primary water filtration system of the RAINBOW vacuum cleaner, capturing any particles that may have been missed.

With its outstanding performance, the HEPA filter contributes to maintaining clean and fresh air quality in your home. Its reusable nature makes it a cost-effective and environmentally friendly choice for long-term use. Experience the benefits of superior air filtration with the RAINBOW vacuum cleaner and its advanced HEPA filter.

Why Does the Rainbow Have a HEPA Filter?

The primary filtration method of the Rainbow Vacuum Cleaner is through its water basin, where dirty air with particles is trapped in the water. However, in certain situations, some particles may escape the water basin and pass through the separator. These cases can occur when the water in the Rainbow becomes too thick and ceases to be liquid due to the accumulation of dirt and grime, or when the vacuum is used with a low water level. To address these situations, the Rainbow incorporates a HEPA filter.

The HEPA filter serves as an additional layer of filtration when the water is no longer capable of retaining all the dust. It effectively filters the air, capturing even smaller particles, and acts as an odor remover as well. It is essential to always use the Rainbow Vacuum Cleaner with the correct water level and prevent the water from turning into sludge.

HEPA Filter Differences

When it comes to HEPA filters, there are key differences to consider, primarily based on the size of particles they can filter, measured in microns. Additionally, HEPA filters can also be differentiated by whether they are washable and reusable or not.

Particle Filtration Size:

HEPA filters vary in their ability to capture particles of different sizes. The efficiency of a HEPA filter is determined by its Minimum Efficiency Reporting Value (MERV) rating. Higher MERV ratings indicate a higher level of filtration efficiency. For example, HEPA filters with a MERV rating of 17 can capture particles as small as 0.3 microns, while filters with a lower MERV rating may capture larger particles but may not be as effective in filtering out smaller ones.

Washable and Reusable:

Some HEPA filters are designed to be washable and reusable, offering long-term cost savings and environmental benefits. These filters can be cleaned periodically to remove accumulated dust and particles, extending their lifespan and maintaining optimal filtration efficiency. On the other hand, non-washable HEPA filters need to be replaced when they become clogged or reach the end of their lifespan.

Beware of non-genuine HEPA Filters

Don’t fall for cheap imitations of HEPA filters being sold by unauthorized retailers or online. The problem with these filters is that they are of poor quality and are mostly manufactured in China. They filter out dust much less effective than the original, and they easily fall apart or get damaged due to the high force and volume of air expelled by the Rainbow vacuum cleaner. The worst part is that you won’t realize the filter is damaged until it’s too late, as the HEPA filter is always enclosed and hidden from view.

Moreover, these non-genuine filters cannot be washed like the original. As a result, they will only last for a few months at best. The original HEPA filter, although two or three times more expensive, is significantly more efficient. It can be washed and, with proper care, can last for many years.

Don’t compromise on the quality and effectiveness of your vacuum cleaner’s filtration system. Choose the original HEPA filter for superior performance and durability.

How to Identify a Non-Original HEPA Filter?

It’s easy to spot non-original HEPA filters that are not manufactured by Rexair. A key indicator is the absence of the ‘Made in USA’ mark stamped on the external casing of the filter. Always check for the ‘Made in USA’ inscription; if it’s missing, the filter is likely made in China and, consequently, not an authentic Rexair product.

Care of the HEPA Filter

The key to maintaining and prolonging the lifespan of your HEPA filter is to ensure that your Rainbow Vacuum is always filled with the correct water level. While using the vacuum, regularly check the water level and prevent it from turning into mud or becoming too thick due to excessive dirt. In such cases, simply empty the dirty water and refill it with clean water to continue your cleaning routine. If you have a considerably large home, it is advisable to purchase a larger water basin, with a capacity of one gallon, available and sold separately for cleaning extensive spaces. This way, your water will last longer and remain clean.

If you use the Rainbow for air purification or aromatization purposes, always make sure that it has the correct water level. Over time, the water in the basin will evaporate, causing the level to decrease. Check it frequently and only use water, disinfectants, and fragrances approved by Rexair or recommended on our website. Do not use any other type of unauthorized or non-recommended disinfectants, detergents, bleach, alcohol, or liquids.

Inspect your HEPA filter every 6-8 months, and if necessary, you can wash and dry it following the instructions provided in this post on how to clean the HEPA filter. Rexair recommends washing the HEPA filter every 2 years and replacing it with a new one after a maximum of 5 years.

Note: It’s important to always follow the manufacturer’s guidelines and recommendations for optimal performance and longevity of your Rainbow Vacuum and HEPA filter.
