Are you tired of dealing with filters that don't last and leave your humidifier less effective? Look no further than the Honeywell C Replacement Filter.

It's designed to reduce minerals in the water and prevent white dust. With a prefilter layer that removes large particles and provides support, this filter maximizes moisture output.

In this article, we'll explore the pros and cons of the Honeywell C Replacement Filter, including feedback from users who have experienced odor and mold issues.

Key Takeaways

  • The Honeywell C Replacement Filter is a reliable and long-lasting option for maintaining the humidity level in a room.
  • Generic filters proved to be less effective, lasting only a few weeks and not performing as well as the Honeywell filters.
  • The blue filter of the Honeywell C Replacement Filter initially emitted a noxious odor, which improved over time but was still present.
  • Some customers find the cost of the Honeywell filters to be expensive and wish they were more affordable.

The Honeywell C Replacement Filter offers several advantages over generic filters for your humidifier.

When comparing the two options, I found that the generic filters didn't last long, only a few weeks at most, while the Honeywell filters lasted me the entire fall and winter dry spell.

Additionally, the generic filters didn't perform as well, resulting in a lower humidity level of around 28% that I couldn't raise. In contrast, the Honeywell filters maintained a solid humidity level between 35-56%.

Another issue I encountered with generic filters was the noxious odor emitted by the blue filter, which permeated my house and aggravated asthma. Although the odor is less pronounced now, it's still present.

These drawbacks make the Honeywell C Replacement Filter a better choice for ensuring optimal performance and avoiding unpleasant odors.

Design and Size

Now let's delve into the design and size of the Honeywell C Replacement Filter – what makes it stand out? The Honeywell C Replacement Filter features an optimized design that maximizes moisture output, ensuring effective humidification. It also includes a prefilter layer that not only removes large particles from the air but also provides additional structural support for the filter. This ensures its durability and longevity.

To provide a clear comparison, here is a table highlighting the design and size features of the Honeywell C Replacement Filter:

This table allows you to easily assess the design features and size specifications of the Honeywell C Replacement Filter, making it a convenient and reliable choice for maintaining optimal humidity levels in your home.


When it comes to filters, you'll want to consider the performance and longevity of the Honeywell C Replacement Filter. This filter is designed to help reduce minerals in the water and white dust, providing cleaner air and maximizing moisture output.

Here are some key features of the Honeywell C Replacement Filter:

  • Protec Treated Filter: The prefilter layer removes large particles from the air and provides additional structural support.
  • Optimized Design: The filter is optimized to maximize moisture output, ensuring optimal performance of your humidifier.
  • Compatibility: The Honeywell C Replacement Filter is compatible with various Humidifier Models, including Honeywell and Duracraft models.

With its long-lasting performance and ability to maintain a solid humidity level, the Honeywell C Replacement Filter stands out from generic filters. Customers have reported positive experiences, with the filter lasting the entire fall/winter season. However, some customers have mentioned an odor issue with the blue filter, which can be a downside.


To further evaluate the performance of the Honeywell C Replacement Filter, let's examine its CADR (Clean Air Delivery Rate) and ACH (Air Changes per Hour) capabilities.

The CADR of a filter measures its efficiency in removing pollutants from the air. The higher the CADR, the faster and more effective the filter is at cleaning the air. Unfortunately, the CADR rating for the Honeywell C Replacement Filter isn't provided, making it difficult to assess its performance in this regard.

As for ACH, it refers to the number of times the air in a room is completely replaced with fresh air in one hour. Higher ACH values indicate better air circulation and faster removal of pollutants. Again, the Honeywell C Replacement Filter doesn't specify its ACH capabilities, making it challenging to determine its effectiveness in this aspect.

Without this crucial information, it's hard to gauge the filter's performance in terms of air cleaning and circulation.

Customer Ratings

Continuing with the evaluation of the Honeywell C Replacement Filter, let's now delve into the customer ratings for this product.

Here are some key points to consider based on customer feedback:

  • Many customers have had a positive experience with the Honeywell brand. They've reported that the two filters in the pack have lasted them the entire fall/winter dry spell and have maintained a solid humidity level in the room.
  • On the downside, some customers have experienced an odor issue with the blue filter. The odor was initially strong and permeated the house, causing discomfort for those with asthma. While the odor has decreased over time, it's still present.
  • Some customers have also voiced concerns about the cost of the filters, finding them to be expensive compared to other options available in the market.
