Humidity, Moisture and Dehumidifiers

Moisture in Buildings Studies

Among various climate related causes that affect buildings is moisture. Not only that, studies that come back to middle 90s shown that 75–80% of all the problems with building envelopes are due to a certain extent to moisture. Later on in 2002, a finding of a cross-sectional analyses done in Finland by Haverinen is really surprising : 38% of detached houses and 25% of apartments were experiencing notable or important moisture issues. In the same year in Sweden (Wessén, Honkanen, Mälarstig, 2002), a study of more than 400 buildings found that 65% of the buildings were having moisture problems. Moisture had led to the growth of microbes in these buildings. These studies have without a doubt risen the awareness of many scientists and should therefore do the same to everyone of us.

Solutions to Indoor Humidification

Today, many people go right to buy a device to cope with humidification problems and doesn’t look for natural dehumidification means. These devices are called dehumidifiers and which are designed to remove indoor moisture by dehumidifying air of the room. This is done by condensing water which is in vapor form, and collecting it in a tank in a first step. The second step is to get air back to the room in its same temperature level. Frigidaire dehumidifiers are one of the most rated units of this category and some models could dehumidify up to 70 pints of water per day.

Examples of Most Common Moisture-related Problems

While some of the examples listed below are very obvious, many people are not aware of the danger of some simple dysfunctions in our homes and which are directly connected to moisture.\

  • Water on the roof or walls coming from rain which often results in mould growth
  • Plumbing is sometime not properly designed or installed which results in spills and leaks.
  • When fixing a plumbing problem, it may have been nicely installed but after maintenance, some plumbing problems may persist or arise.
  • When weather is warm and humid, you may experience an infiltration of warm or moist from outside entering through crack in the enclosure.
  • The opposite effect could happen as warm or moist could get outside your home through holes in the enclosure and which can result in condensation in your house´s walls or ceiling.

What is an air purifier ?

When first hear this name, you think that it’s a big machine which is used in industrial and medical industries, but in fact this is no longer the case. Air Purifiers are now small and even portable and are mainly made to remove airborne germs and other impure air particles like tobacco smoke, dust particles etc….

Does Air Purifiers work ?

When reading the benefits of an Air purifier on its box or on advertisements, you have the impression that it’s a guess game because of the amount of information that focuses more on the cleraning process of the air than what happens to the body. And to answer that question, according to an article from the New York Times, Dr.Myatt reported that it did work after having observed that visits to the doctor of asthmatic children had reduced right after having used an purifier. Yes it is mainly used to stop allergy symptoms, but at least we have an answer about asthma from an expert.

Indoor Dust Solutions for Home, Office and Workshop

Whether it’s at work, at school or at home, constantly sneezing, wheezing, and coughing is a nightmare for allergy sufferers. Many approaches to allergy problems had been developed going from simple avoidance therapy to very sophisticated technology devices designed for different environments and allergen particle types. Dust is the most common trigger of allergy symptoms, but not only for real allergy sufferers, but for everybody. At work or at school, this could impede significantly the productivity and efficiency of working or learning. Not to mention the uncomfortable state caused by these particles that the sufferer and also people that are close to him endure.
In this article i have gathered different indoor dust solutions for different environments including home, workshop, office and more.

At Home


While a vacuum cleaner is a solution to indoor dust control, the filters that comes with the conventional vacuums, and also the ones that are designed with a container of water, emit thin particulates into the air.This is why having a vacuum cleaner that comes with a HEPA filter is a greater choice. Except if you have one of these high-quality vacuums that fulfil the task almost like HEPA filter vacuums. In this case you may think to add more security by having an air purifier that will, in addition to your quality vacuum, purify your air. But in case you have not a high-performance vacuum, then getting a vacuum cleaner that has HEPA filter like Dyson Vacuums is better protection against dust particles.

In Your Workshop


In these kind of environment, not having the suitable solution could lead to serious health problems, asthma for example. I will take the woodwork shop as an instance as it is one of the environment where dust particles are largely spread in the air.When a woodworker uses a drill you can imagine the amount of dust particles spread in the air, you may not sneeze at the moment but for an everyday use this will become more dangerous. Sometimes limiting the exposure is not enough. This is why engineers thought of a dust collection system that accompany woodworkers in these kind of environment. From the first model of these, this industry has advanced in term of ergonomy and technology. The Festool dust extractor is one of these successful state of art when it comes to dust collection and ease of use.

In the Office


Unless your office is located in a big company that already accomplish the cleaning task, you must look for an easy solution to your discomfort. Yes you can’t stand and take a vacuum cleaner and start chasing dust, but there is a piece of technology that do it, not as effectively, for you and in a quiet way and without moving: the air purifier. This device not only deals with dust particulates, but also with tobacco smoke and airborne germs. But for the office you better choose a suitable one that looks serious and blends nicely with the work environment. Germguardian air purifier is one of the best choices. Black, sleek, and is a bestseller on Amazon.
