Winix

Pros

• Widely available aftermarket filters that are significantly cheaper than OEM versions

• Units are often reported to last for several years of continuous operation

Cons

• Frequent reports of fan bearing failure leading to whistling or whining noises

• The PlasmaWave ionizer can sometimes produce a noticeable smell and may reset to 'on' automatically
• Bright LED indicators can be disruptive at night and may require physical covering
