Product Notes:

New packaging for Blue Pure 411 particle + carbon filter

The BLUE Pure 411 and Blue Pure 411 Plus from Blueair use two types of filters:
* the main 2-in-1 Particle + Carbon Filter common to all three 411 models, which combines a particle filter to capture contaminants as small as 1 micron with an odor-eating activated carbon sheet inside that to reduce gaseous pollutants and odours (note, this filter has just been released in a different box style, as shown here); and,
* a prefilter made of stretchy fabric to trap larger particles such as dust or pet hair, which comes in a variety of colours to fit in with many décors. The ones made for the 411+ come in 6 colours. Those are characterized as being incompatible with the original 411 (since they are slightly bigger, to fit over the protective mesh grill on the Plus model), but since they have to be stretched to pull on either model, we have found that the 411+ filters do fit fine on the 411 models, as well.

Main Filter

The main filter is designed to remove a wide variety of pollutants and irritants including bacteria, dust, mold spores, pollen, and pet dander, as well as light airborne chemicals, gases, and cooking odours, using a combination of particle and activated carbon filters. This same filter can used by both the original 411 and the 411+ and the new 411 Auto model, as well by the model called the JOY S in some markets, and a completely different earlier model called the MINI.

Prefilters

Like the stretchy prefilters on the exterior of the Blueair BLUE Pure 211 (which have five of the same colours: the 411+ adds one: Saffron Red), these pre-filters help extend the life of the main filter by fitting over them to trap the larger particles or other airborne debris as it passes though.

They are designed to last indefinitely; you simply need to vacuum them every few weeks when you see them accumulating a lot of dust, hair, or ashes, etc., and they can also be machine washed just as pantyhose or tights can. (They fit on much the same way, and the fabric label on the 211 versions indicate they are composed of 93% nylon and 7% spandex.) But they will eventually show signs of wear, and you may also want some in other colours to match different rooms or user preferences, so you can certainly get more here.

How to Change the Main Filter

When your unit notifies you it's time to replace your filter after about six months of use (via a colour change on the speed indicator lights on top), it's not hard to do.

On the original 411 model, as shown in this video starting at about the 3 minute mark, you simply have to push down slightly on the top portion of the air purifier and turn it counterclockwise to remove the head; peel off the fabric prefilter; lift off the plastic filter retaining ring; hold the tabs on top of the old main filter and lift it off the plastic frame it fits around ... and then reverse that process using the new filter.

On the 411+ model, it's a bit different: you actually need turn the air purifier upside down to change it from the bottom. Once again, you simply turn the cap there counterclockwise and remove it to access the old filter; you remove the prefilter, take out the old filter, vacuum away any dust you might see there on the inside, and then open up and insert the replacement filter inside the metal grill, and replace the prefilter and the cap. There are more detailed instructions and a diagram taken from the User Manual for this, below.

(Of course, you need to unplug the unit first, in both cases.)

Directions for replacing main filter in Blueair Blue Pure 411 Plus

Directions for Changing Main Filter on the 411 Plus:

1) When the indicator lights turn red (typically after 6 months of continuous operation) it is recommended that you change the main filter.

2) Turn off the unit and unplug it.

3) Remove the prefilter from the unit's metal frame.

4) Carefully place the unit upside down on a flat surface and open the bottom lid by rotating it counter-clockwise while holding another part of the unit.

5) Remove that opened bottom lid.

6) Grip the two handles/flaps on the main filter and pull upwards to remove it from the unit.

7) Open up / unfold the new main filter into a cylindrical shape and position it into the metal frame. Ensure that it retains that cylindrical shape by pressing it against the metal frame from inside the unit.

8) Replace the bottom lid by gently pushing it down and simultaneously rotating it clockwise to secure it back into the bayonet lock.

9) Turn the unit back into its correct upright position, and place on the floor in an appropriate location for operation (away from sources of heat, no closer than 10cm/4" to other objects, and where air can circulate freely).

10) Plug it back in and turn on the 411+ unit.

11) Press the button on top of the unit and hold for 5 seconds to reset the filter replacement timer. (This lets the unit know you have changed the filter.) The indicator light should flash 3 times, and then change from red to white.
