FAQ Hunter Air Purifier Troubleshooting

Hunter Air Purifier Troubleshooting Guide

Why Is My Hunter Air Purifier Making A Strange Noise?

If your Hunter air purifier is making a strange noise, there could be several reasons for it:

Dust Buildup On Ionizer Pins: 

One common reason is that the ionizer pins have dust buildup, causing static electricity and ticking or clicking noise. 

To fix this issue, turn off the device, remove the filter, clean the ionizer pins with a soft brush or cloth, and then replace the filter.

Clogged Or Incorrectly Installed Filter: 

A dirty or clogged filter can cause whistling or unusual noises. Ensure to replace the filter regularly and install it correctly to avoid this issue.

Location Of The Air Purifier: 

The purifier’s location can also affect the noise level. If the purifier is placed in a high-traffic area or near a wall, it can cause more noise. 

Try moving the purifier to a quieter location to reduce the noise.

Inherently Loud Model: 

If none of these solutions work, your air purifier may be simply a loud model. 

Some air purifiers are designed to be louder than others, and there may not be a way to reduce the noise.

In this case, you may want to consider purchasing a quieter model.

To further address the strange noise issue with your Hunter air purifier, consider the following tips:

  • Regular Maintenance: 

Perform regular maintenance on your air purifier, including cleaning the exterior vents and other accessible components, to prevent dust buildup and improve efficiency.

  • Inspect The Fan: 

Inspect the fan for any debris, dust, or misalignment if the strange noise persists. Carefully clean the fan and its housing, or adjust it if necessary.

  • Check for Loose or Damaged Parts: 

Inspect the air purifier for any loose or damaged parts that could be causing the noise. Tighten or replace any problematic components as needed.

  • Consult The User Manual: 

Always refer to your Hunter air purifier’s user manual for specific instructions on troubleshooting and maintenance. The manual may provide additional guidance tailored to your specific model.

What Does Pre-Filter Mean On A Hunter Air Purifier?

A pre-filter on a Hunter air purifier is the first stage of filtration in the device. 

Its purpose is to capture large particles, such as pet hair and pollen, before reaching the main HEPA filter. 

By doing so, the pre-filter prolongs the life of the HEPA filter and improves the overall efficiency of the air purifier.

Located upstream of the primary filter, the pre-filter ensures that the airflow goes through it before touching the main filter. 

After the pre-filter captures the larger particles, the smaller particles that pass through are trapped by the True HEPA filter, which removes up to 99.97% of particles as small as 0.3 microns.

The efficiency of a standard pre-filter ranges between 20% and 70%, and it can capture particles between 3 and 10 microns. This makes it particularly useful for pet owners. 

However, the pre-filter is less efficient than the HEPA filter, which can remove 99.97% of mold, bacteria, pollen, and dust.

Can You Wash Hunter Air Purifier Filters?

According to the Hunter website, washing Hunter air purifier filters is generally not recommended, as it may damage the filter or air purifier.

Instead of washing, SafeWise recommends using a vacuum cleaner to remove dust and debris from air purifier filters. 

Another source mentions that if washing is required, it should involve careful rinsing of the dust from the filter. 

Additionally, a video on YouTube provides tips on how to clean reusable air filters, including washable ones. 

Following the manufacturer’s instructions for your specific Hunter air purifier model is essential to ensure proper care and maintenance.
