Some devices have HEPA-type filters, which work similarly but are not held to the exact same performance standards. The IQAir HealthPro Plus uses a HyperHEPA filter, which is believed to catch even smaller particles than a real HEPA filter.
Your purifier will likely also come with a pre-filter (a few you can wash, some you have to throw after a few weeks ) that grabs the large stuff like pet fur and individual hair until it reaches the primary filter.
Some devices have added filters, such as charcoal or carbon filters, which trap the petroleum-based gases known as volatile organic chemicals (VOCs).

Air purifier sound levels
Air-purifier noise levels vary from nearly silent to steady humming, like an AC unit. Depending upon the fan speed you are using and where you are placing your socket, you may prefer a quieter apparatus.
Air purifier added prices
The cost of your air purifier is 1 thing. Ongoing filter replacement and electricity costs are another. For example, some machines have filters that last for years but are costly to replace, but some work with filters that are inexpensive to buy but have to be changed frequently.
You will also want to think about the expense of electricity. Some of the best air purifiers we recommend are ENERGY STAR certified, but every pulls varying amounts of power on various fan speeds.
Devices for bigger rooms and with greater rates tend to use more electricity. Some devices also have eco friendly modes. The Blue Pure 411 requires the least energy, but it covers only a little room.
Air purifier additional features
Some features are more nice-to-have extras than absolute requirements. Generally, pricier purifiers come with additional features, such as filter indicator lights, dimmable lights and programmable timers.
Only one of those devices we recommend (that the IQAir HealthPro Plus) comes with a remote control, but we’re not convinced that this adds a whole lot of significance to the machine.
