Filter Maintenance Guide
How do I change the filters in my INOVA Air Purifier?
Accessing the Filters
1. Unplug the power cord.
2. Make sure the system is placed on a flat and even surface.
3. Pull the top of the latches (A) away from the main unit on either side.
4. Push the latches back towards the central unit (B)
5. Ensure the latch clasps are clear of catches on the base (C).
6. Lift casing clear of the base to access filters

1. Carbon Filter (excluded in V series)
The Activated Carbon filter can be effective for approx. 1-3 years, depending on the level of chemicals & odours present. The life of this filter can be shortened if exposed to consistently high amounts of chemicals and odours. This filter should be changed when it is saturated, meaning it has entirely adsorbed what it has filtered from the air during use. You can tell when a carbon filter needs changing because the air from the air purifier will either be tainted with an odour of what it has adsorbed during use, or the air will simply stop smelling clean.
More information about the lifespan of the carbon filter can be found here.
2. HEPA Filter
The HEPA filter is designed to last 3 to 5 years under normal use. Like with other filters, the environment in which it is used will determine the filter life. The outside of the HEPA filter will change color and turn grey when it needs changing. Generally, for the first two years of use, the filter will remain white and gradually get darker in the final months of its life. Note: the inside of the HEPA filter will always remain white, so it is important to check the outside of the filter, which is visible when the pre-filter is being changed.
3. Pre-Filter
The pre-filter is wrapped around the HEPA filter & fastened with velcro. Gently unwrap from the existing filter & replace it with the new pre-filter. If you suffer from dust allergies, we recommend taking the system outside before removing the pre-filter to avoid releasing dust in your environment. Alternatively, wear a dust mask if performing this operation inside. Ensure the pre-filter is installed so the ‘fluffy’ Velcro strip faces outwards and is firmly fitted around the HEPA filter to avoid air bypassing the pre-filter. We recommend replacing the pre-filter at least every 6 months. In high dust environments, the pre-filter may need to be changed more frequently.
INOVA E7 Filters
1. Carbon Wrap Filter
The Activated Carbon blanket filter will be effective for 6-12 months. However, its life can be shortened if exposed to consistently high amounts of chemicals and odors. This filter should be changed when saturated, meaning it has filled up with whatever it has filtered from the air during use. You can tell when a carbon filter needs changing because the air purifier's air will either be tainted with an odor of what it has adsorbed during use or the air will stop smelling clean or smell stale.
