What is a particle filter?

The exodraft ESP wood stove filter is designed to filter out hazardous and ultrafine particles from the flue gas of your wood-burning stove or fireplace.

The wood stove filter reduces the number of particles by 95% (fine and ultrafine particles) as well as reducing the total particle mass by 70%-75%.

Measurements were carried out according to the Norwegian standard NS3058 which corresponds to outside air conditions.

The electrostatic particle filter is installed on top of the chimney, where it is coldest, and uses a high-voltage electrode to charge the particles in the flue gas, causing them to collect inside the filter.

The exodraft ESP particle filter comes with a self-cleaning feature and catalytic-like technology.

Retail Price; 2.196 £  (incl. VAT) – Price is excl. mounting and mounting accessories.

Case - Copenhagen, Denmark

In the backyard of one of the villas in Copenhagen, Vibeke
Møller, a psychologist in private practice, has a orangery,
which serves as her practice.

Vibeke has had a woodburning stove installed to heat the
orangery and because she is aware of the issue of particle
emission, she additional has had a filter for woodburning
stoves from exodraft installed.

How to install exodraft Woodstove filter

Watch our installation video which is step-by-step instructions on how to handle and install exodraft’s particle filter.

The video reviews i.a. removal of transportation lock, control of electrode, as well as mounting on steel and brick chimney.

Why should you remove flue gas particles?

Flue gas particles have a size less than 0.1 μm which
is 1000 times smaller than a human hair.

Since the throat of the human body is only capable
of capturing particles larger than 2.5 μm, the smaller
particles continue to lungs and blood vessels, causing
asthma, breathing problems and/or inflammations and
are therefore damaging to your health.

Exodraft’s particle filter captures and eliminates both
large and ultrafine particles, thus minimizes the health risk.

Self-cleaning function

The particles are collected inside the filter by electrostatically charging the particles and trapping
them inside the filter, where the self-cleaning function
of the ESP will cause some of the particlesto combust.

The remaining particles are released into the chimney,
to be burnt off, thus eliminating the need for manual
cleaning of the filter.

A cleaning hatch can be supplied for installation between
the chimney and the filter, if national law requires chimney
sweep access from the top of the chimney.

Integrated chimney fan

The ESP particle filter comes with an integrated chimney fan in its top section.

A chimney fan is a ventilator that ensures a constant updraught in the chimney, making it easier to light the fireplace as well as helping to prevent the backflow of smoke into the room.

Without this reliable mechanical draught, you are at the mercy of the chimney’s natural draught which can vary depending on outside temperature, wind and air pressure.

How does exodraft contribute to the UN sustainable development goal nr. 3?

” Ensuring healthy lives and promoting the well-being
at all ages is essential to sustainable development.”

Both our chimney fans and particle filters for wood-burning
stoves contribute significantly to the reduction of harmful
particles, both within the private home and the outdoors.

In other words, our products aid in fostering health and
well-being wherever they are installed.
