NeoPur 400 replacement filter
Weighing in at 1.7 kg (3.7 lbs), the NeoPur 400 filter is a multi-layer filter that comes chock full of high-efficiency technologies, giving it a broad spectrum of action and making it effective against all forms of air pollution.
The NeoPur 400 filter (compatible with AIRVIA ORIGIN 40) is composed of 5 different layers: 1) pre-filter, 2) antibacterial filter, 3) HEPA H13 filter, 4) activated charcoal filter, and 5) photocatalysis. Note that the UVC lamps and ioniser are separate and do not need to be replaced on a yearly basis.
The air first passes through a pre-filter, followed by a filter made of natural bamboo fibre that is sprayed with an antibacterial agent. Next, it goes through a certified HEPA H13, medical-grade filter. HEPA stands for ''High Efficiency Particulate Air and is a European certification requiring that 99.97% of fine particles (down to a size of 0.01 micron) are removed in a single pass. The next steps are the activated charcoal filter and a photocatalysis layer to remove all chemical pollution.
Easy replacement
The NeoPur 400 multi-layer filter can be changed with ease directly by the user in under a minute thanks to a built-in hatch. Simply lift the old filter out of the hatch, swap it with the new one, and enjoy your renewed clean air. No need for a technician.

FAQs
Please read our FAQs page to find out more.
How often should I replace my NeoPur 400 filter?
The NeoPur 400 filter (compatible with AIRVIA ORIGIN 40) requires a change every 12 months. Refer to our article on why it is essential to replace your filters at regular intervals here.
Note that our Eoleaf air purifiers (as well as those manufactured by AIRVIA Medical) are equipped with multi-layer filters. All of the layers are contained within the same filter block, meaning that you will not need to change several filters at different intervals.
Why is it so important to change my NeoPur 400 filters regularly?
Overtime, the NeoPur 400 filter (equivalent of the AIRVIA ORIGIN 40 filter) gradually becomes saturated with pollution, which can cause the device's motor to overwork and degrade. Additionally, if you continue using a saturated NeoPur 400 filter (AIRVIA ORIGIN 40 filter equivalent), it may start releasing the pollutants that it has captured and stored back into the air. Filters have a shelf life, even when they are not being used, because they interact with their surrounding air.
You will find a detailed article on this question on this page here.
Does the Eoleaf NeoPur 400 require changing multiple filters?
No! Compared to many of our competitors, all of our 8 filtration technologies are contained within one filter block. This means no need to keep separate filter change schedules and no need to purchase separate filters. Simply change the NeoPur 400 filter (AIRVIA ORIGIN 40 equivalent), once per year.
